What is the short circuit withstand rating ( Isc ) for ( GV2G445 ) ?
This bus bar does not have a conditional short-circuit rating. The short-circuit current withstand is compatible with the breaking capacity of motor protection circuit breakers GV2** with which the bus bar is used.
So the Isc of the GV2G** depends on the GV2ME/P energized ratings. You can use a circuit breaker or fuses in upstream of the GV2G445 for a short circuit value up to 11KA as the permissible peak current of GV2G445 is 11KA. ( See attachment).
