What Is An AC Contactor For Air Conditioners?

Ac contactor is an electrical switching device, which is mainly used to control the switching of motors, compressors and fans in the air conditioning system. Xiaobian take you to introduce our company's AC contactor this product

The role of AC contactor of air conditioning
When the air conditioning system needs to run, the AC contactor will close the circuit and transfer power to the corresponding equipment, thus starting the operation of the air conditioning system. In the air conditioning system, AC contactor plays a very important role, this product can control the start and stop state of the motor, compressor, fan and other equipment in the air conditioning system to ensure the stable operation of the air conditioning system.

The working principle of AC contactor of air conditioning
The working principle of AC contactor of air conditioning is based on the principle of electromagnetic induction and electromagnetic suction. The product structure includes a contact, a coil and an electromagnetic magnetic aid system. When the control circuit is energized to the coil of the contactor, the magnetic field generated in the coil will attract the iron core in the contactor, so that its contacts are closed or cut off, and the load circuit is controlled. When the coil is energized, the magnetic field generated by the coil winding will act on the iron core, and under the action of electromagnetic induction, the iron core will be subjected to the action of suction, so that its contact is closed. When the coil is powered off, the magnetic field of the iron core disappears and the contact opens because of the spring force. In this way, the closure and disconnection of the contact are controlled by controlling the on-off of the coil, which is used to control the load circuit.

The importance of air conditioning AC contactor
In the air conditioning system, AC contactors are often used to control the compressor and fan of the air conditioner, which can realize the switch and temperature control of the air conditioner, ensure the normal operation of the air conditioner, and improve the energy-saving performance of the air conditioner. Due to the characteristics of high reliability, large capacity, sensitive action, long service life and easy installation, AC contact equipment is often used in the field of industrial automation and power control.

Air conditioning AC contactor maintenance
When the air conditioner system is not in use for a long time, check the AC contactor of the air conditioner regularly to avoid affecting the normal use of the air conditioner. You should also clean the dust and dirt on the contactor regularly to keep the product as clean as possible to ensure normal subsequent operation.
