What devices make up motor control?

Contactors switch the motor circuit, overload relays protect against running overload, and protection breakers combine these roles in some units.

How is a starter assembled?

A contactor switches the motor, an overload relay guards it, and control wiring sequences start and stop.

Why is overload protection needed?

It stops the motor before sustained overload damages the winding, using a curve set to the motor current.

What is the contactor rating based on?

The rating follows the motor full-load current and the switching duty class of the application.

Where are these used?

They are used in starter panels, machine feeders, and motor control centres.
