Introduction to Power System Contactor
A power system contactor is an electrically controlled switch used for switching an electrical power circuit. It is designed to handle high - current loads and is commonly used in industrial, commercial, and residential electrical systems. Contactors are crucial components in power distribution, motor control, and other electrical applications as they can make and break circuits safely and efficiently. They typically consist of a coil, contacts, and an enclosure. When the coil is energized, it creates a magnetic field that pulls the contacts together, closing the circuit. When the coil is de - energized, the contacts open, interrupting the current flow.
