M1 circuit breaker MCCB
Product Description :
M1 series of moulded case circuit breaker is one of our new type products developed and manufactured by adopting international advanced technology. It is supplied with rated insulating voltage 660V and used for circuit of A.C.50Hz, rated operating voltage AC 380V(or below). Rated operating current up to 1250A for infrequency over and shtarting of the motors. Equipement with the pritection devices for over current, short circuit and undervoltage.
Standard IEC/EN60497-2 and GB14048.2
