APPELICATION:

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.

We are specialized in producing circuit breaker for over 10 years.and have rich production and development experience,Otherwise,our product are comply with the international standard of IEC 60947-2. ISO9001-2000.and we are sure our product will meet the client as to their requirement
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.
