ASKM2E Intelligent Electronic Molded Case Circuit Breaker for General Protection

ASKM2E Intelligent Electronic Molded Case Circuit Breaker for General Protection

ASKM2E intelligent electronic molded case circuit breaker(hereinafter referred to as MCCB) is a new type of circuit breaker designed and developed byour company using international advanced technology. MCCB is suitable for the distribution network of AC 50Hz, rated insulation voltage 1000V, ratedvoltage 400V and rated current up to 1250A. MCCB can be used for infrequent switching of lines and infrequent starting of motors.

MCCB have 3-section protection function(LSI, i.e. overload long delay protection+short-circuit short delay protection+grounding protection ), 4-section protection function(LSIG, i,e. overload long delay protection+short-circuit short delay protection+short-circuit instantaneousprotection+grounding protection ) and under-voltage protection function. MCCB can protect circuits and power equipment from damage. Lowtemperature to -40"C type circuit breaker is available.
