250A 3P MCCB circuit breaker

oem provide good quality

DZ20L  series molded case circuit breaker (hereinafter referred to as circuit breaker) is suitable for circuit of AC 50Hz , rated insulation voltage 660V, rated working voltage 380V (400V) or below and rated current from 16A to 1250A. The circuit breakers take the role of infrequent turn-on or turn-off and infrequent motor start-up. The breakers have over-load, short-circuit and under-voltage protection performances so to protect the circuit and power appliance from damage. The breaker could be installed vertically(upright) or horizontally(transverse). The breaker could not be wired adversely,1,3 and 5 can only be connected with power line,2,4 and 6 con only be connected with load line.
