CM1-630 AC MCCB Molded case circuit breaker
1.Application Area
CM1 series molded case circuit breaker are mainly applied to distribution system of 50HZ,rated insulation voltage 690V,rated current up to 1250A.It's purpose lays in power system distributing & protecting against malfunctions such as overload,short-circuit,undervoltage,etc.It also can be used as infrequent ON/OF switch under power system in normal conditioin.
Sorted by ultimate short-circuit breaking capacity,CM1 breakers can be defined as Model L(standards type),& Model M(high breaking capacity type).They're well-known for compact shape,high breaking capacity and short flashover distant,etc.
CM1 breakers can be either vertically or horizontally installed.
CM1 breakers comply to GB14048.2 standards,with CCC,CE approved.
