| ASKB1 normal protection type miniature circuit breaker has features as advanced structure, reliable performance, high breaking capacity, beautiful and compact appearance, etc. Shell and three parts are made of impact resistant and high flame retardant materials. ASKB1 are suitable for AC 50Hz or 60Hz, rated operational voltage below 400V, rated current below 125A. MCB are mainly used for the overload and short-circuit protection of lines and equipment in lighting and power distribution in office buildings, residences and similar buildings. Under normal conditions, MCB can also be used in infrequent on-off control of electrical devices and lighting lines. Through adding internal components with different functions , we provide residual current protection type MCB, over-voltage under-voltage protection type MCB and prepaid meter special type MCB. |
