Magnetic Contactors
An electromagnetic contactor is an electrical component that turns on and off a load current. It is used in a wide range of applications such as use in motors, lamps, and heaters and can open and close the main circuit by remote control to start and stop a device. It features a main contact connected to the wiring on the power supply side and the load side, and an auxiliary contact for the self-holding circuit. It has a mechanism that the contacts are activated by electromagnetic force. When a built-in coil is electrified, a movable core is drawn to a fixed core, and at the same time, the contacts come into contact and the circuit opens. Reversible products that can switch the motor rotation to reverse rotation are also available. The larger the load, the larger the size of the electromagnetic contactor and the size of the main contact, so select an appropriate one as needed.
