Product Details
CMTW1 series air circuit breaker is applicable for power distribution network with AC50/60 Hz, rated voltage 400/415/600/690V, and rated current 200~6300A. This circuit breaker has intelligent protection function and accurate selective protection, it improves reliability of power supply and avoids unnecessary power failure. Such ACB can divide the power and protect the line and power device from overload, under- voltage ,short circuit ... CMTW1 can be mainly used in power stations, factories, mines and modern high-rise buildings with smart power distribution system. The product conforms with the standard of IEC/EN 60947-2.| Model NO. | CMTW1 | CMTW1 | |||
