MHZW1 intelligent circuit breaker

MHZW1 series intelligent universal circuit breaker is suitable for distribution network with AC 50Hz, rated working voltage 400V, 690V, rated current 630A to 6300A, used to distribute electric energy and protect lines and power equipment from overload, undervoltage, short circuit, ground fault hazard. The circuit breaker adopts an intelligent controller with precise selective protection and multi-function, with complete protection functions, especially suitable for distribution networks that need to improve the reliability of power supply and avoid unnecessary power outages. Among them, the 2H and 3H type controllers have communication interfaces, which are convenient for connection with the field bus, and can realize the four remote functions of "telemetry", "remote adjustment", "remote control" and "remote communication" to meet the requirements of control automation, and configure leakage mutual inductance. The device and the corresponding intelligent controller can realize leakage protection. The circuit breaker with a rated working current of 1000A and below can also be used in the AC 50Hz, 400V network as the overload, short circuit, undervoltage and ground fault protection of the motor, and can be used for the infrequent starting of the motor under normal conditions.
