YKM1 series of molded case circuit breaker (short for circuit breaker),AC50/60HZ,Current :63-800A,Voltage:400V,500V,690V,800V..

YKM1 series of molded case circuit breaker (short for circuit breaker), is the latest circuit breaker of advanced technology. The insulation voltage is 800V, (YKM1-63: 500V), used for the circuit of rated working voltage 690V and below, (YKM1-63: 400V), rated working current 800A to infrequently transfer and infrequently starting. The circuit breaker have the functions of overload, short circuit and undervoltage protection which can protect the circuit and power equipment from damage.
