The CM1 series circuit breaker is mainly used for overload, undervoltage, and short circuit protection of distribution lines and power equipment in distribution networks with AC frequency of 50Hz-60Hz, rated insulation voltage of 800V, rated working voltage of 690V and below, and rated current of 1250A and below. Plastic shell circuit breakers with 400A shell level and below can also be used for motor overload, undervoltage, and short circuit protection. Under normal circumstances, it can be used for infrequent switching of circuits and infrequent starting of motors.
This series of circuit breakers has the characteristics of small size, high short-circuit breaking capacity, small arcing distance, and anti vibration. When the overload current or short-circuit current reaches or exceeds its specified value, the circuit breaker will automatically trip, thereby cutting off the power supply and protecting the equipment on the load side.
Special Model Description:
Type C: Basic, able to meet basic requirements;
S-type: Standard type (equivalent to L-type) suitable for use in power systems with 10 times the current and most occasions;
M-type: higher breaking type, used for motor starting and protection, and power cabinet;
H-type: High segment type, suitable for 12 times trip current and motor protection;
