Detailed Product Description


WCM1 series moulded case circuit breaker (MCCB) is a new product of circuit breaker series which adopts the international advance designation, technology R&D. The rated resulating voltage is 800V(WCM1-63 is 500V). Mount in the circuit of AC50Hz, R. operating volotage below 690V(WCM1-63 is 400V), R. current up to 800A for utility of switch-on and switch-off motor not frequently. The breaker can keep the motor from damage when overload, short circuit or lack of voltage.

The breaker has 4 types according to the difference of R. ultimate short-circuit breaking capacity. They are type C(lower), L(standard), M(higher), H(highest). The breaker has characteristics of small volume, high breaking capacity, short arc distance(some types has no arc distance), vibration resistance, etc. They are the ideal product for land and ship use.

Executive standards:

IEC60947-1 AND GB/T14048.1 GENERAL

IEC60947-2 AND GB/T14048.2 LOW VOLTAGE CIRCUIT BREAKER

IEC60947-4 AND GB/T14048.4 CONTACTOR AND THE STARTER OF MOTOR
