New Design 4000A 3P Fixed Type ACB Air Circuit Breaker
Application of Intelligent Air Circuit Breaker(ACB)
Yueqing Aiso 4000A 3P Fixed Type ACB Air Circuit Breaker according to the guarantee of production, ensure the copper bar size, to ensure that the product has a good performance in the work. The newly designed ACB makes the appearance more beautiful and the operation more convenient.
DW45 series universal circuit breaker(hereinafter referred to as breaker)is suitablefor the circuit of AC 50Hz with rated voltage 400V, 690V and rated current up to 6300A.It is mainly used to distribute electric energy and protect circuits and power-supplyequipment from overload, under-voltage, short-circuit and single-phase earthing. withintelligentized and selective protection functions, the breaker can improve the reliabilityof power supply, and avoid unnecessary power failure. The breaker is applicable forpower stations, factories, mines(for 690V) and modern high-buildings, especially for thedistribution system of intelligentized building. This breaker conforms to IEC60947-2 andGB14048.2. The whole series have past CCC certifi cation.
