Connecting and installation<br />
Power <strong>circuit</strong><br />
Is connected using Cu or Al busbars or cables, and possibly<br />
cables with cable lugs.<br />
To have more options, connecting sets are made (see page<br />
E7 for detailed information)<br />
Generally, conductors from the supply are connected<br />
to input terminals 1, 3, 5 and conductors from the load to<br />
terminals 2, 4, 6. But it is possible to reverse the connection<br />
(exchanging input and output terminals without limiting<br />
rated short-<strong>circuit</strong> ultimate breaking capacity I cu<br />
).<br />
In case of reversed connection, in the majority of cases,<br />
<strong>circuit</strong> breaker/<strong>switch</strong>-disconnector must be fitted with<br />
OD-BHD-KS02 insulating barriers also on the side of<br />
terminals 2, 4, 6 (see page E22 for detailed information).<br />
We recommend painting the connecting busbars.<br />
Input and output connectors/busbars must be<br />
mechanically reinforced in order to avoid transferring<br />
electrodynamic forces to the <strong>circuit</strong> breaker during<br />
short <strong>circuit</strong>ing.<br />
The way of connecting the power <strong>circuit</strong> must<br />
observe the deionization space of the <strong>circuit</strong> breaker/<br />
<strong>switch</strong>-disconnector (see page E23).<br />

Recommended <strong>circuit</strong> breaker manipulation<br />
During the manipulation with <strong>circuit</strong> breaker in plug-in design<br />
with motor drive, the <strong>circuit</strong> breaker may reach the state,<br />
in which the first attempt at <strong>switch</strong>ing-on by motor drive is<br />
unsuccessful. Switching-on is executed after repeated make<br />
pulse. To avoid this effect, some of the following steps may<br />
be done:<br />

OVERCURRENT RELEASES<br />
3P<br />
4P<br />
The electronic overcurrent release consists of a separate and interchangeable<br />
unit, which is supplied with the BD250... <strong>switch</strong>ing<br />
unit. By exchanging the overcurrent release, the range of<br />
the <strong>circuit</strong> breaker’s rated current can be easily changed.<br />
Overcurrent releases for BD250... <strong>switch</strong>ing units are produced<br />
in current values of I n<br />
= 100, 160 and 250 A. The<br />
L001 releases are produced with rated currents of 160, 200<br />
and 250 A. The releases (including regulation of -60%) cover<br />
a current range from 40 to 250 A.<br />
Depending upon the needs for adjusting the release’s tripping<br />
characteristic to the protected device and to the variability of<br />
the characteristic with regard to selectivity, the following release<br />
devices are available:<br />
L001<br />
They have one type of characteristic and fixed I n<br />
and I rm<br />
settings.<br />
DTV3<br />
They have one type of characteristic with adjustable I r<br />
and I rm<br />
.<br />
MTV8<br />
They have more kinds of characteristics with adjustable I r<br />

L001, DTV3, MTV8 and MTV9 overcurrent releases are intended<br />
for 3-pole, BD250..305 <strong>switch</strong>ing units and 4-pole, BD250..405<br />
<strong>switch</strong>ing units with disconnecting of the N pole.<br />
4D01<br />
Are intended for 4-pole, BD250..406 <strong>switch</strong>ing units with<br />

L001, DTV3, MTV8, MTV9 and 4D01 - description of function<br />
Proper functioning of releases does not depend on the form<br />
of current in the power <strong>circuit</strong>. The function of the release is<br />
supported by a microprocessor, which processes a sampled<br />
signal of the power <strong>circuit</strong> and recalculates it to obtain an<br />
rms value. Therefore, the releases are suitable for protecting<br />
<strong>circuit</strong>s where the sinusoidal current is distorted by high harmonics<br />
(e.g. <strong>circuit</strong>s with controlled rectifiers, power factor<br />
compensators, pulse loading, and the like).<br />
Setting the tripping characteristic<br />
The tripping characteristic of the overcurrent releases is<br />
defined by standard EN 947-2. For releases DTV3, MTV8,<br />
MTV9 and 4D01, the characteristic is adjusted using latched<br />
<strong>switch</strong>es on the overcurrent release unit.<br />
A visual demonstration on setting the tripping characteristic<br />
can be found in the SICHR program (see www.oez.com) .<br />

achieve selectivity of protective devices. For MTV9 releases, the<br />
delay can be set at 0, 100, 200 or 300 ms.<br />

OVERCURRENT RELEASES<br />
1. Dependent release (thermal) L<br />
The dependent release DTV3 is adjusted using one I r<br />
<strong>switch</strong>. The I r<br />
<strong>switch</strong> is used to adjust the <strong>circuit</strong> breaker’s<br />
rated current, with the characteristic shifting on the current<br />
axis. By means of its internal <strong>circuit</strong>ry, the release is set to<br />
one type of characteristic.<br />
The dependent releases MTV8, MTV9 and 4D01 are adjusted<br />
using two <strong>switch</strong>es, I r<br />
and t r<br />
. The first (I r<br />
) <strong>switch</strong> is used<br />
to adjust the <strong>circuit</strong> breaker’s rated current. The characteristic<br />
is moved on the current axis.<br />
By turning the other <strong>switch</strong> (t r<br />
), the time is adjusted after<br />
which the <strong>circuit</strong> breaker will trip while passing through 7.2 I r<br />
.<br />
The tripping characteristic thus moves on the time axis. Using<br />
the t r<br />
<strong>switch</strong>, it is possible to set a total of 8 characteristics. For<br />
MTV8 and MTV9 releases there are available 4 characteristics<br />
for motor protection and 4 characteristics for protecting lines.<br />
Breaking times correspond with the release class 10 A, 10, 20,<br />
30. By changing t r<br />
, it is possible to select the characteristic according<br />
to the required motor starting (light, medium, heavy<br />
or very heavy starting). For 4D01 releases, there are available<br />
8 characteristics for protecting lines or transformers. It is not<br />
possible to turn the device back on right after the dependent<br />
release has been actuated and <strong>circuit</strong> breaker tripped. The<br />
release must be allowed to cool off, because it has a thermal<br />
memory. The memory can be disabled by turning the <strong>switch</strong><br />
from the normal “T t<br />
” position to the “T 0<br />
” position. The dependent<br />
release remains active, and only its thermal memory is<br />
inactivated. Switching off the thermal memory should be used<br />
only in well-justified cases, and with the knowledge that there<br />
could be rising temperature in the protected device with repeated<br />
tripping.<br />
2. Delayed independent release S<br />
This release is only in the MTV9 overcurrent releases. The<br />
delayed independent release has the function of a delayed<br />
short-<strong>circuit</strong> release. It is used to set up a selective cascade of<br />
<strong>circuit</strong> <strong>breakers</strong>. It is set up using parameters I rmv<br />
and t v<br />
. I rmv<br />
is<br />
an n-multiple of current I r<br />
(I rmv<br />
= n × I r<br />
). It is a short-<strong>circuit</strong><br />
current that, within the span of I rmv<br />
to I rm<br />
, will trip the <strong>circuit</strong><br />
breaker with delay t v<br />
, where t v<br />
is a delay set up for <strong>switch</strong>ing<br />
off the release. The delayed independent release actuates the<br />
<strong>circuit</strong> breaker if the current in the <strong>circuit</strong> reaches at least the<br />
preset n-multiple and lasts at least the preset delay time t v<br />
.<br />

Tripping characteristics of L001, DTV3, MTV8, MTV9 and<br />
4D01 releases with load<br />
The tripping characteristic from the cold state indicates the tripping<br />
times during which it is assumed that, up to the moment<br />
Example<br />
The shortening constant can be read from the graph. With<br />
steady current 85% of I r<br />
the real tripping time will be<br />
shortened to:<br />
when an overcurrent develops, no current is flowing through<br />
the <strong>circuit</strong> breaker. The tripping characteristic tripped from t s<br />
= 0,74 . t v<br />
warm state indicates the tripping times during which it is assumed<br />
that, before the moment when an overcurrent develops,<br />
current is flowing through the <strong>circuit</strong> breaker. Characteristics of<br />
electronic releases are independent of the ambient temperature<br />
and are plotted in a cold state. Digital releases enable simulation<br />

The SE-BD-....-MTV8 release is intended for BD250...<br />
<strong>switch</strong>ing units. The operation of the release is controlled by a<br />
microprocessor. The release is equipped with a thermal memory<br />
that can be disabled by turning a <strong>switch</strong> on the front panel<br />
from position T (t)<br />
to position T (0)<br />
. After disabling of the thermal<br />
memory, the thermal release remains active.<br />
When one or two phases fail (due to current greater than I r<br />
in the<br />
remaining phases), in the M-characteristic mode, the <strong>switch</strong> will<br />
open with a 4 s delay (so-called undercurrent release).<br />
Another parameter for adjusting the release consists of the rated<br />
current and short-<strong>circuit</strong> tripping level. The time delay of the<br />
short-<strong>circuit</strong> release can be set to 0 or 50 ms. The operational<br />
state 70% of I r<br />
is signalled by an LED indicator that flashes green<br />
in a 1.5 s interval. As the load grows, the blinking frequency of<br />
the diode increases. In case of a load larger than 110% of I r<br />

The releases have tripping characteristics especially designed<br />
for practical purposes that provide for optimal exploitation of<br />
transformers up to 1.5 I r<br />
. A total of 8 characteristics can be set<br />
on the release. Mode “M” provides 4 characteristics suitable<br />
for protecting motors and in mode “TV” are 4 characteristics<br />
for protecting transformers and lines. The shape of each<br />

Direct protection for motors and generators<br />
Possibility for protecting lines and transformers<br />
Enables adjusting time delay of independent release<br />
Description<br />
The SE-BD-....-MTV9 release is intended for BD250...<br />
<strong>switch</strong>ing units. The operation of the release is controlled<br />
by a microprocessor. The release is equipped with a thermal<br />
memory that can be disabled by turning a <strong>switch</strong> on the front<br />
panel from position T (t)<br />
to position T (0)<br />
. After disabling of the<br />
thermal memory, the thermal release remains active.<br />
When one or two phases fail (due to current greater than I r<br />
in the remaining phases), in the M-characteristic mode, the<br />
<strong>switch</strong> will open with a 4 s delay (so-called undercurrent<br />
release).<br />
Another parameter for adjusting the release consists of the<br />
rated current and tripping level of the delayed short-<strong>circuit</strong><br />
release. The time delay (t v<br />
) can be set on the delayed short<strong>circuit</strong><br />
release at 0, 100, 200 or 300 ms. The operational state<br />
70% of I r<br />
is signalled by an LED indicator that flashes green in a<br />
1.5 s interval. As the load grows, the blinking frequency of the<br />
diode increases. In case of a load larger than 110% of I r<br />
, this<br />
LED will turn red and just before tripping will begin to blink<br />
red. On the lower part of the release cover are two photocells<br />
for communicating with the prospective signalling unit.<br />
The releases have tripping characteristics especially designed<br />
for practical purposes that provide for optimal exploitation of<br />
transformers up to 1.5 I r<br />
. A total of 8 characteristics can be set<br />
on the release. Mode “M” provides 4 characteristics suitable<br />
for protecting motors, and in mode “T V<br />
” are 4 characteristics<br />
for protecting transformers and lines. The shape of each<br />
characteristic can be changed using a selector <strong>switch</strong>.<br />

Protecting lines and transformers in TN-C-S and TN-S networks<br />
Description<br />
The SE-BD-....-4D01 release is intended for the BD250..406<br />
<strong>switch</strong>ing unit. The operation of the release is controlled by<br />
a microprocessor. The release is equipped with a thermal<br />
memory that can be disabled by turning a <strong>switch</strong> on the<br />
front panel from position T (t)<br />
to position T (0)<br />
. After disabling<br />
of the thermal memory, the thermal release remains active.<br />
The rated current I r<br />
, delay for <strong>switch</strong>ing off the release at<br />
7.2 I r<br />
, and the tripping level of the short-<strong>circuit</strong> release can<br />
be adjusted.<br />
The operational state is signalled by an LED indicator that<br />
flashes green in a 1.5 s interval. As the load grows, the blinking<br />
frequency of the diode increases. In case of a load larger than<br />
110% of I r<br />
this LED will turn red and just before tripping will<br />
begin to blink red. On the lower part of the release cover<br />
are two photocells for communicating with the prospective<br />
signalling unit.<br />
The current of the fourth pole (N pole) is adjusted using the<br />
IN <strong>switch</strong> as a multiple of the I r<br />
current. Measuring of current<br />
on the fourth pole can be disabled by turning the button to<br />
the “OFF” position.<br />

HAND DRIVES<br />
Description<br />
The hand drive makes possible to govern the <strong>circuit</strong> breaker/<br />
<strong>switch</strong>-disconnector by pivoting lever, e.g. to <strong>switch</strong> machines<br />
on and off. Modular conception of drives makes possible simple<br />
mounting on the <strong>switch</strong>ing unit (also additionally) after<br />
the cavity cover is removed. A fixed motor is possible to seal.<br />
The drive and its accessories is ordered separately according to<br />
your choice, see page E11.<br />
The hand drive makes possible to control the <strong>circuit</strong> breaker:<br />
a) from the front panel of the <strong>circuit</strong> breaker (Fig.1)<br />
Hand drive unit RP-BD-CK..<br />
+ Hand drive lever RP-BHD-CP..<br />

+ Extension shaft RP-BHD-CH..<br />
+ Hand drive bearing PR-BHD-CN..<br />
+ Hand drive lever + RP-BHD-CP..<br />
Fig. 1 - DIMENSIONS see page E29<br />
The hand drive unit is fixed right on the <strong>switch</strong>ing unit of<br />
the <strong>circuit</strong> breaker.<br />
The hand drive bearing is fixed onto the <strong>switch</strong>board<br />
door and it provides protection IP40 or IP66.<br />
The hand drive lever is placed on the hand drive unit or on<br />
the hand drive bearing.<br />
The extension shaft is supplied in two options, standard<br />
(length 365 mm – can be cut short) and telescopic (adjustable<br />
length 245 ÷ 410 mm)<br />
Enhanced safety for operator:<br />
The hand drive unit and hand drive lever are also supplied with<br />
the possibility to lock the <strong>circuit</strong> breaker in position „<strong>switch</strong>ed off<br />
manually“. The unit and lever of the hand drive can be locked<br />
using three padlocks with shank diameter max. 6 mm.<br />
Each hand drive bearing prevents the door from opening<br />
when the <strong>circuit</strong> breaker is on-state or off-state by releases<br />
and types RP-BHD-CN40 and RP-BHD-CN41 when the <strong>circuit</strong><br />
breaker is in the state <strong>switch</strong>ed off manually and hand drive<br />
lever is locked up.<br />
Two <strong>circuit</strong> <strong>breakers</strong> with hand drives can be provided with<br />
mechanical interlock or with parallel mechanical <strong>switch</strong>ing, see<br />
page E67.<br />

RP-BHD-CB10 Mechanical interlocking<br />
Provides mechanical interlocking of two <strong>circuit</strong> <strong>breakers</strong>/<br />
<strong>switch</strong>-<strong>disconnectors</strong> so that they cannot both be tripped<br />
simultaneously, but only one of them at a time. Both <strong>circuit</strong><br />
<strong>breakers</strong> may be turned off simultaneously. Interlocking can<br />
be used between two BD250 <strong>circuit</strong> <strong>breakers</strong> or between<br />
BD250 and BH630 <strong>circuit</strong> <strong>breakers</strong>. Both <strong>circuit</strong> <strong>breakers</strong> must<br />
be furnished with a hand drive (at least one with a hand drive<br />
unit and hand drive lever), see page E66.<br />
In order to use the interlocking, it is absolutely necessary to<br />
comply with the dimensions shown in the figure and table.<br />

MECHANICAL INTERLOCKING<br />
Mechanical interlocking<br />
MB-BD-PV05<br />
MB-BHD-PV03<br />
3P<br />
4P<br />
Provides mechanical interlocking of two <strong>circuit</strong> <strong>breakers</strong>/<br />
<strong>switch</strong>-<strong>disconnectors</strong> so that they cannot both be tripped<br />
simultaneously, but only one of them at a time. Both <strong>circuit</strong><br />
<strong>breakers</strong> may be turned off simultaneously.<br />
Mechanical interlocking MB-BD-PV05 is intended for<br />
two BD250 <strong>circuit</strong> <strong>breakers</strong>. Interlocking MB-BHD-PV03 is<br />
intended for one BD250 <strong>circuit</strong> breaker and one BH 630.<br />
Circuit <strong>breakers</strong> may be in fixed, plug-in and withdrawable<br />
designs.<br />

Recommended <strong>circuit</strong> breaker manipulation<br />
During the manipulation with <strong>circuit</strong> breaker with mechanical<br />
interlocking and motor drive, the <strong>circuit</strong> breaker may reach<br />
the state, in which the first attempt at <strong>switch</strong>ing-on by motor<br />
drive is unsuccessful. Switching-on is executed after repeated<br />
make pulse. To avoid this effect, some of the following steps<br />
may be done:<br />
1) To keep the process of manipulation with the <strong>circuit</strong> breaker,<br />
see „Recommended <strong>circuit</strong> breaker manipulation“ below<br />
2) To connect auxiliary relays into the motor drive <strong>circuit</strong><br />
according to wiring diagram, see page E74<br />
3) To connect OD-BHD-R… control relay into the motor<br />
drive <strong>circuit</strong> according to wiring diagram, see page E76<br />
Recommended <strong>circuit</strong> breaker manipulation<br />
1) For <strong>switch</strong>ing-off the <strong>circuit</strong> breaker, shunt trip<br />
(undervoltage release) must be used. Switching-off the<br />
<strong>circuit</strong> breaker cannot be made by motor drive.<br />
2) Circuit breaker can be stored and <strong>switch</strong>ed on only if the<br />
second <strong>circuit</strong> breaker is in <strong>switch</strong>-off mode. Circuit breaker<br />
status indicator on motor drive is in „O“ position. Between<br />
storing and <strong>switch</strong>ing-on the <strong>circuit</strong> breaker, it is necessary<br />
to keep the time interval min. 100 ms. Switch „S“ must be<br />
disconnected.<br />
3) In case of infringement of these principles, the first<br />
<strong>switch</strong>ing-on of <strong>circuit</strong> breaker is unsuccessful.<br />

DIMENSIONS see page E30<br />
Description<br />
The motor drive is part of <strong>circuit</strong> breaker accessories enabling<br />
you to <strong>switch</strong> the <strong>circuit</strong> breaker on and off remotely. Modular<br />
conception of the drives enables simple mounting on the <strong>circuit</strong><br />
breaker (also additionally) after the <strong>circuit</strong> breaker cavity cover<br />
is removed. The fixed motor can be sealed. Modeion <strong>circuit</strong><br />
<strong>breakers</strong> with motor drives can be used in the most demanding<br />
industrial applications such as protection of standby sources,<br />
synchronization of two sources, etc. and anywhere it is<br />
necessary to ensure automated and unmanned operation of<br />
electrical equipment. The motor drives are equipped with<br />
spring storage units and due to accumulated energy to trip the<br />
<strong>circuit</strong> breaker, it is no problem to trip the <strong>circuit</strong> <strong>breakers</strong> within<br />
times up to 50 ms. Releasing of the storage unit and tripping<br />
of the <strong>circuit</strong> breaker is ensured by a closing coil that belongs<br />
to standard equipment of every motor drive. The time before<br />
the <strong>circuit</strong> breaker is tripped using the motor drive is 800 ms.<br />
This method of tripping is suitable for controlling technological<br />
entities. When faster <strong>circuit</strong> breaker tripping is required (e.g.<br />
emergency STOP push button), it is possible to use the motor<br />
drive in combination with undervoltage release or shunt trip.<br />
On the motor drive front panel there is a selector <strong>switch</strong> to<br />
select the drive modes with a possibility to indicate remotely the<br />
selector <strong>switch</strong> state. The first mode is automatic remote control<br />
(selector <strong>switch</strong> in position AUTO). This is the standard position<br />
in automatic operation. The second mode is manual control<br />
(selector <strong>switch</strong> position MANUAL), the motor drive does not<br />
need any voltage to perform its function.<br />
Remote <strong>switch</strong>ing on and off in position AUTO is carried out<br />
using push buttons that must be connected to the drive unit<br />
connector, furthermore, this position makes it is possible to<br />
control the <strong>circuit</strong> breaker with the push buttons on the drive<br />
unit front panel.<br />
In MANUAL mode it is possible to <strong>switch</strong> on and off using<br />
the green and red push buttons on the front panel of the motor<br />
drive cover. The function of the remote control ON push button in<br />
MANUAL mode is locked up, whereas the function of the remote<br />
control OFF push button remains active for safety reasons.<br />
Specifications<br />
The motor drive, apart from the <strong>circuit</strong> breaker, recognizes<br />
only two fixed positions. In the first position the <strong>circuit</strong> breaker<br />
is ON. When the <strong>circuit</strong> breaker is tripped in AUTO mode<br />
by overcurrent releases or auxiliary trips, then because of<br />
mechanical link between the <strong>circuit</strong> breaker and the drive, a<br />
pulse will be generated to wind up the spring of the storage<br />
unit automatically, depending on operator`s demand, by<br />
permanent closing of <strong>switch</strong> S or after the <strong>circuit</strong> breaker is<br />
checked by <strong>switch</strong>ing S <strong>switch</strong> on. In the second fixed position<br />
the <strong>circuit</strong> breaker is <strong>switch</strong>ed off and the loaded drive is ready<br />
to <strong>switch</strong> the breaker on after it has received the setting pulse.<br />
The motor drive makes possible to control the <strong>circuit</strong> breaker<br />
after the loss of control voltage. In MANUAL and AUTO modes,<br />
it is possible to wind up the storage unit by repeated rotation<br />
of the foldable handle. After the storage unit is wound up, it<br />
is possible to <strong>switch</strong> the <strong>circuit</strong> breaker on and off using the<br />
control buttons on the front panel of the drive.<br />
On the front panel there is a storage unit status indicator<br />
indicating locally what state the drive unit storage is in and<br />
whether it is possible to <strong>switch</strong> the <strong>circuit</strong> breaker on. BH<br />
motor drives enable to obtain a storage status signal from the<br />
terminal strip also remotely. BD drives have optional designs,<br />
alternatively with MANUAL / AUTO indication.<br />
The drive can be furnished with an electromechanical<br />
operations counter that may be installed in the drive cover or<br />
fixed beyond the <strong>circuit</strong> breaker space (e.g. in the <strong>switch</strong>board<br />
door) or in the <strong>switch</strong>board space using a metal holder included<br />
in the supply of external operations counter and its connecting<br />
can be done using connectors.<br />
The drive can be locked in off position using as many as three<br />
padlocks with shank diameter max. 4.3 mm.<br />
An OD-BHD-KT01 cover can be affixed to the drive`s turnon<br />
<strong>switch</strong> and then sealed. The cover prevents turning on the<br />
<strong>circuit</strong> breaker from the drive panel.<br />
Extension cable OD-BHD-KA02 has a connector on one<br />
side that connects to the connector on the motor drive and<br />
conductors on the other side that connect, for example, to a<br />
terminal block.<br />
