Description
A Magnetic Contactor and a Circuit Breaker are essential electrical devices used in power distribution and motor control systems. They work together to provide safe operation, automatic switching, and circuit protection in industrial and commercial applications.
1. Magnetic Contactor
A Magnetic Contactor is an electrically controlled switch used to control the power supply to motors, lighting systems, and industrial machines. It operates using an electromagnetic coil that pulls the contacts together when energized, allowing current to flow.
Features of a Magnetic Contactor
Automatic Operation – Opens and closes circuits remotely.
High Durability – Designed for frequent switching operations.
Reliable Performance – Ensures smooth motor and power control.
Arc Suppression – Reduces electrical arcing to extend lifespan.
Variety of Coil Voltages – Available in AC & DC versions.
Overload Protection – Can be paired with thermal relays for safety.
