3200A Air Circuit Breaker AC 690V ACB

1. Application

ACB(Air circuit breaker) is suitable for the circuit of AC 50Hz with rated voltage up to 690V and rated current up to 6300A. It is mainly used to distribute electric energy and protect circuit and power supply equipment from overload, under voltage, short circuit and single phase earthing with intelligentized and selective protection function, the breaker can improve the reliability of power supply and avoid unnecessary power failure. The breaker is applicable for power stations, factories, mines (for 690V) and modern high-buildings, especially for the distribution system of intelligentized building. The whole series have past CCC and CE certification.
