Things 

will never be 

the same 

To ensure a continuous supply of electrical power, certain 

installations are connected to two sources: 

b a normal source N 

b a replacement source R used to supply the installation 

when the normal source is unavailable. 

A source-changeover system switches the load between 

these two sources. It can be automated to manage transfers 

according to external conditions. A source-changeover system 

includes two or three circuit breakers or switch-disconnectors. 

With Interpact INS, Compact NS and Masterpact NT and NW, 

new installation solutions are available to optimise the size of 

the switchboard and simplify installation.

Manual source-changeover system 

This is the most simple type. It is controlled manually by an operator and 

consequently the time required to switch from the normal to the replacement 

source can vary. 

A manual source-changeover system is made up of two or three mechanically 

interlocked manually-operated circuit breakers or switch-disconnectors. 

Remote-operated source-changeover system 

This is the most commonly employed system for devices with high ratings (above 

400 A).No human intervention is required. Transfer from the normal to the 

replacement source is controlled electrically. 

A remote-controlled source-changeover system is made up of two or three circuit 

breakers or switch-disconnectors linked by an electrical interlocking system that 

may have different configurations. In addition, a mechanical interlocking system 

protects against electrical malfunctions or incorrect manual operations. 

Automatic source-changeover systems 

An automatic controller may be added to a remote-operated source-changeover 

system for automatic source control according to programmable operating modes. 

This solution ensures optimum energy management: 

b transfer to a replacement source according to external requirements 

b management of power sources 

b regulation 

b emergency source replacement, etc. 

The automatic controller may be fitted with an option for communication with a 

supervisor.

Interlocking of two or three toggle-controlled devices 

Two devices can be interlocked using this system. Two identical interlocking systems 

can be used to interlock three devices installed side by side, in which case one 

device is in the ON position and the two others are in the OFF position. Devices must 

all have the same configuration, i.e. fixed, plug-in, withdrawable or drawout. 

The system is locked using one or two padlocks (shackle diameter 5 to 8 mm). 

Two interlocking system models are available for: 

b Compact NS100 to 250 

b Compact NS400 to 630.

Interlocking of a number of devices using keylocks (captive 

keys) 

Interlocking is based on two identical keylocks with a single key and a keylock 

adapter (different for each device). This solution enables interlocking between two 

devices that are physically distant or that have very different characteristics, for 

example between a low and a medium-voltage device, or between Compact NS 

circuit breakers and switch-disconnectors. 

A system of wall-mounted captive key boxes makes possible a large number of 

combinations between many devices. 

Combination of “Normal” and “Replacement” devices 

All Interpact, Compact and Masterpact circuit breakers and switch-disconnectors from 100 to 

6300 A with rotary handles or motor mechanisms can be interlocked. 

Interlocking of two devices on a base plate 

A base plate is available for mechanical interlocking of two manually-operated 

Compact circuit breakers or switch-disconnectors.

Complete source-changeover assembly for two switchdisconnectors 

These assemblies provide an easy way to implement source changeover functions with: 

b a single 3-position rotary handle that controls the two switch-disconnectors 

(Normal source ON, OFF, Replacement source ON) 

b a smaller size, taking up less room in the switchboard. 

A complete source changeover assembly can be ordered with a single catalogue 

number..

Functions 


Electrical interlocking is used with the 

mechanical interlocking system. It 

electrically interlocks the two circuit 

breakers and implements the time delays 

required for proper operation of the system. 

An automatic controller may be added to 

take into account information from the 

distribution system. 

E88002 



Electrical interlocking 

Electrical interlocking is carried out by an electrical control device. 

For Compact NS up to 630 A, electrical interlocking is implemented by the IVE unit 

integrating control circuits and an external terminal block. The integrated control 

circuits implement the time delays required for correct source transfer. 

For Compact NS630b to 1600 and Masterpact, this function can be implemented in 

one of two ways: 

b using the IVE unit 

b by an electrician based on the diagrams presented in the “Electrical diagrams” 

part of this catalogue. 

Characteristics of the IVE unit 

b external connection terminal block: 

v inputs: circuit breaker control signals 

v outputs: status of the SDE contacts on the “Normal” and “Replacement” source 

circuit breakers 

b 2 connectors for the two “Normal” and “Replacement” source circuit breakers: 

v inputs: 

- status of the OF contacts on each circuit breaker (ON or OFF) 

- status of the SDE contacts on the “Normal” and “Replacement” source circuit 

breakers 

v outputs: power supply for operating mechanisms 

b control voltage: 

v 24 to 250 V DC 

v 48 to 415 V 50/60 Hz - 440 V 60 Hz. 

The IVE unit control voltage must be same as that of the circuit breaker operating 

mechanisms. 

IVE unit. 

Necessary equipment 

For Compact NS100 to 630, each circuit breaker must be equipped with: 

b a motor mechanism 

b an OF contact 

b an SDE contact. 

The components are supplied ready for assembly and the circuit breakers 

prewired. The prewiring must not be modified. 

For Compact NS630b to 1600, each circuit breaker must be equipped with: 

b a motor mechanism 

b an available OF contact 

b a CE connected-position contact (carriage switch) on withdrawable circuit 

breakers 

b an SDE contact.

from 0.1 to 30 seconds). 

t2. delay between detection that the “Normal” source has returned and the 

transmission of the order to open the “Replacement” source circuit breaker 

(adjustable from 0.1 to 240 seconds). 

Circuit breaker commands and status indications 

The status of the circuit breakers is indicated on the front of the controller. 

c ON, OFF, fault. 

A built-in terminal block may be used to connect the following input/output signals: 

c inputs: 

v voluntary order to transfer to source R (e.g. for special tariffs, etc.) 

v additional control contact (not part of the controller). Transfer to the 

“Replacement” source takes place only if the contact is closed (e.g. used to test the 

frequency of UR, etc.) 

c outputs: 

indication of operation in automatic or stop mode via changeover contacts. 

Test 

It is possible to test the operation of the BA controller by turning OFF (opening) the 

P25M circuit breaker for the “Normal” source and thus simulating a failure of

Operating modes 

A four-position switch may be used to select: 

b automatic operation 

b forced operation on the “Normal” source 

b forced operation on the “Replacement” source 

b stop (both “Normal” and “Replacement” sources off, then manual operation). 

Setting the time delays 

Time delays are set on the front of the controller. 

t1. delay between detection that the “Normal” source has failed and the 

transmission of the order to open the “Normal” source circuit breaker (adjustable 

from 0.1 to 30 seconds). 

t2. delay between detection that the “Normal” source has returned and the 

transmission of the order to open the “Replacement” source circuit breaker 


t3. delay following opening of QN with load shedding and before closing of QR 


t4. delay following opening of QR with load reconnection and before closing of QN 


t5. delay for confirmation that UN is present before shutting down the engine 

generator set (adjustable from 60 to 600 seconds). 

t6. delay before startup of the engine generator set (120 or 180 seconds). 

Commands and indications 

Circuit-breaker status indications on the front of the controller: 

ON, OFF, fault. 

A built-in terminal block may be used to connect the following input/output signals: 

b inputs: 

v voluntary order to transfer to source R (e.g. for special tariffs, etc.) 

v additional control contact (not part of the controller). Transfer to the 

“Replacement” source takes place only if the contact is closed (e.g. used to test the 

frequency of UR, etc.) 

b outputs: 

v control of an engine generator set (ON / OFF) 

v shedding of non-priority circuits 

v indication of operation in automatic mode via changeover contacts. 

Distribution-system settings 

Three switches are used to: 

b select the type of “Normal” source, whether single-phase or three-phase (e.g. 

240 V single-phase or 240 V three-phase) 

b select whether to remain (or not) on the “Normal” source if the “Replacement” 

source is not operational during operation on special tariffs 

b select the maximum permissible startup time for the engine generator set during 

operation on special tariffs (120 or 180 seconds). 

Test 

A pushbutton on the front of the controller may be used to test transfer from the 

“Normal” source to the “Replacement” source, then the return to the “Normal” 

source. The test lasts approximately three minutes. 

COM communications option 

Using the internal bus protocol, this option may be used to remote the following 

information: 

b circuit-breaker status (ON, OFF, fault trip) 

b presence of the “Normal” and “Replacement” voltages 

b presence of an order for forced operation (e.g. special tariffs) 

b settings and configuration information 

b status of non-priority circuits (loads shed or not) 

b position of the switch (stop, auto, forced operation on the “Normal” source, forced 

operation on the “Replacement” source).
