CM1) series moulded case circuit breakers are one of the new breakers designed and developed by our company by comprehensively adopting advanced technology. Rated insulation voltage of this series of breakers are up to 800V. It applies to distribution network circuit of AC 50Hz or 60Hz with rated working voltage up to 690V and rated working current up to 800A. It is used to protect circuits and powersupply equipment form damage of overload, under-voltage, short-circuit etc, can also be used for infrequent start of motor and provide overload, short circuit and under-voltage protection for the motor. This breaker features small volume, high breaking capacity, short arc time, an ideal product to use. This breaker can be installed both vertically and horizontally. This product complies with standard of IEC 60947-2. Classifications 1. According to breaking capacity of MCCB: L(standard type), M(relatively higher breaking type), H(high breaking type) 2. According to connection mode of MCCB: Front panel connection (basic connection mode), rear panel connection, plug-in connection 3. According to operation mode: Direct handle operation (basic operation mode), rotary handle operation, motor operation 4. According to number of poles: 3 poles, 4 poles.
