3 Pole Molded Case Circuit Breaker , Enclosed Molded Case Switch
63Amps150Amps 400AmpsMccb Breaker Triple Pole. Breaking Capacity 35 Ka for bids tenders
SM1moulded case circuit breaker with rated insulation voltage800V, applied in the power system of AC50(60)Hz, rated voltage 690V and below, rated current 1250A and below as the transfer not frequently. The circuit breaker has the protection devices of overload, short circuit , and under-voltage,it can protect the circuit and power equipment from broken.
The MCCB can be sorted into C type (basic), L type (standard), M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity.
The MCCB has the features small volume, breaking capacity high, electric arcing short,anti-vibration. It is the ideal product for application on land and ship.
The installation can be vertical or level and the standard conforms to IEC60947-2 and GB14048.2
