ASKM2 Thermal-Magnetic Molded Case Circuit Breaker for General Protection

ASKM2 Thermal-Magnetic Molded Case Circuit Breaker for General Protection

ASKM2 thermomagnetic molded case circuit breaker(hereinafter referred to as MCCB) is a new type of circuit breaker designed and developed by ourcompany using international advanced technology. The rated insulation voltage of MCCB is 1000V. MCCB is suitable for the distribution network ofAC50/60Hz, rated voltage 690V and below, rated current 10A-1250A. MCCB can distribute power and protect circuits and power equipment against faultslike overload, under-voltage, short-circuit and under-voltage. MCCB can also be used for infrequent switching of lines and infrequent starting ofmotors. The products have the characteristics of small volume, high breaking capacity, short flying arc, vibration resistant, etc. The whole series haveisolation function.
