For connection of auxiliary circuits, the circuit breakers of fixed version are equipped with manually plug-in<br />
terminal boards with coding pins, which eliminate misuse of the terminal boards in their connecting with<br />
the block of the citcuit breaker blade contacts.The contacts of auxiliary circuits of circuit breakers of<br />
withdrawable version are inserted automatically in circuit breaker moving into the frame.<br />
Conductors of auxiliary circuits are connected to terminal boards in two ways (see the figure).<br />

Overcurrent protection settings<br />
Adjust parameters only when the circuit-breaker is switched off. If the<br />
parameters are modified with the circuit-breaker switched on, this can<br />
!trip the circuit-breaker unintentionally.<br />
All parameters are adjusted with rotary coding switches.<br />
3 x 0,5<br />
The value 0,1 is set<br />
if the rotary switch is<br />
positioned in this zone.<br />

Contact assemblies need to be changed according their condition, but at least after:<br />
-10 000 Operations in FSI and FSII;<br />
-5 000 Operations in FSIII;<br />
-1 000 Operations in FSII and FSIII when used in 1000 V appliances<br />
The switchgear operator has to be determine inspection intervals depending on the breaker<br />
applications:<br />
-min. 1x per annum<br />
-after interruption of heavy loads<br />
-after trips by the overcurrent release (trip unit)<br />
-down stream connected non-automatic circuit breakers have to be inspected also<br />
During the inspection and/or after 1000 switching operations, the following items must be examined<br />
(max. operations see catalog):<br />
-arc chutes and contact systems<br />
-electrical and mechanical functionaliy of the breaker<br />
-mechanical on- / off-functionality<br />
-main and auxiliary circuits, function and connecting quality<br />
-plausibility control of trip unit settings and correction, if necessary<br />
If the breaker endurance is exhausted, then the breaker and old spare parts are to be disposed of,<br />
according to the effective legal regulations.<br />
Draw-Out guide frames with arc-chute covers installed, have to be replaced after no more than three<br />
schort-circuit interruptions of the circuit-breaker.<br />
The arc chutes and the contact system must be replaced depending upon their condition, but latest after<br />
10,000 switching operations.<br />
Depending on the circuit-breaker stress it may also be necessary to replace the operating system after<br />
10,000 switching operations.<br />
The attached CD contains more detailed operating instructions.<br />
Only materials which have low adverse environmental impact and which do not contain dangerous<br />
substances as specified in ROHS directive have been used in the product.<br />
