ASKM2L Thermal-Magnetic Molded Case Circuit Breaker for General Protection

ASKM2L Thermal-Magnetic Molded Case Circuit Breaker for General Protection

ASKM2L thermomagnetic leakage protection intelligent molded case circuit breaker(hereinafter referred to as MCCB) is a new type of circuit breakerdesigned and developed by our company using international advanced technology. MCCB is suitable for the distribution network of AC 50Hz, ratedinsulation voltage 1000V, rated voltage 400V and rated current up to1250A. MCCB can be used for infrequent switching of lines and infrequent startingof motors.

MCCB has overload, short-circuit and under-voltage protection, can protect the line and power supply equipment from damage. Protection can alsobe provided against fire hazards that may be caused by long- standing ground faults that cannot be detected by over-current protection.
