Product Description

APPLICATION
SWM1 moulded case circuit breaker with rated insulation voltage 800V, 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 over load, short circuit and under voltage ,it can protect the circuit and power equipment from broken.

The mccb can be sorted to 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 in land and ship.

The installation can be vertical or level and the standard conforms to IEC60947-2 and GB14048.2
