Magnetic contactor has the primary function of opening and closing electrical circuits to supply high-power loads. Its operation uses a magnetic field from an electromagnet coil to pull contacts into circuit connection when current flows through the coil, and releases the contacts back to their original state when there is no current flow. It can be used as a main circuit breaker in various systems such as motor starting and stopping, water pump control, lighting systems, and industrial work.
The main components of Magnetic contactor include the following:
