Application
CYM6-CW moulded case circuit breaker is rated insulation voltage 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 power-supply equipment from damage of overload, short circuit and under-voltage protection for the motor, can be installed both vertically and horizontally.
This breaker has features of small volume, high breaking capacity, short arcing time, an ideal product to use. This product complies with standard of IEC 60947-2.
