The air conditioning AC contactor is a switching device used to control the AC power supply in the air conditioning system. It is an electromagnetic switch that controls the closing and opening of the main contact by turning the electromagnetic coil on and off, thereby realizing the start and stop control of air conditioning compressors, fans and other components. The main functions of the air-conditioning AC contactor include: controlling the start and stop of the air-conditioning compressor and protecting the compressor from frequent starts and stops. Cooperate with the air conditioning control system to realize automatic control of air conditioning. In the event of overload, short circuit and other faults, promptly cut off the power supply to protect the safety of the air conditioning system. Cooperate with other protection devices, such as overload relays, pressure switches, etc., to improve the reliability of the air conditioning system. Specification:
