What is the use of AC contactor?

AC contactors are mainly used to control large currents in AC circuits and have a wide range of uses, including: controlling the start and stop of motors, reversing and speed regulation, controlling the on and off of heating equipment and temperature adjustment control, lighting switches and dimming control The solenoid valve switches on and off to start and stop pumps and fans, control rolling shutter doors and hoists, and serves as a switching element in the automatic control system

## AC contactor

1. Control the motor

Start and stop the motor
Reverse the motor running direction
• Change the motor speed

2. Control the heating equipment

Control the heating element On and off
• Adjust heating temperature

3. Control lighting

Switch lighting circuit
• Control lighting Brightness

4. Control the solenoid valve

Control the on and off of fluid or gas

• Control roller shutters and winches
• Used as switching elements in automatic control systems
• AC contactor consists of coil, contacts and frame. When the coil is energized, electromagnetic force causes the contacts to close, thus completing the circuit. When the coil is de-energized, spring force causes the contacts to open, breaking the circuit. By controlling the on and off of the coil, the opening and closing of the main circuit can be easily controlled.

AC contactors usually have high rated current capacity and can work reliably under high voltage and high current conditions. They also offer the advantages of durability and long service life.
