The short-circuit current withstand rating (KA) of Tesys Comb Busbar is compatible with the breaking capacity of Motor Protection Circuit Breakers (MPCB) of GV series. The GV Series Comb Busbar does not have a conditional short-circuit current rating.
The maximum permissible peak current for GV2G*** Series Comb Busbar is 11KA and for GV3G*64 series Comb Busbar is 20KA.
Example: Use a circuit breaker or fuse in upstream of the Tesys GV2G for a short circuit value up to 11KAmps as the permissible peak current of GV2G354 is 11KA.
