Pole Contactor

What is an Electrical Contactor?

What exactly is an electrical contactor?
Can a three pole contactor be used in a single phase circuit?

A contactor is an electrical component for switching on and off the power by creating an open circuit.
There is a coil of fine copper wire surrounding a ferrous material (iron) plunger which. When a current is applied to the coil the resulting electromagnetic force pushes the plunger in or out, causing the contactors to open or close.
Depending on what voltage the coil of the contactor is you can use a three phase contactor on a single phase circuit.
Check that the voltage rating for the contacts and the coil as they may be different.
