Ac contactors – Definition & Types

An Ac contactor is an electromechanical switch whose function is to make or break the connection between the power supply and the load. Ac contactors operate as an on-off switch as they have a built in surge suppression. They are frequently used in electrical products and power systems to control large-load industrial equipment. As a general-purpose switching device, ac contactor allows electronic circuits to control current and electrical equipment like controlling motors, heaters, control circuits or lights. Ac contactors are unlike circuit breakers, they remain closed and conduct current continuously until they either receive a command to open or automatically disconnects due to a malfunction.

A typical ac contactor consists of a coil of copper wire wound around an iron core, actuated by a movable ferromagnetic armature bar assembly that has electrical contacts. When a dc voltage is applied across the coil, it generates an electromagnetic force that pulls the armature bar inwards. Moving the bar internally closes the contacts and establishes the connection between supply and load. There are various types of ac contactors like solid state contactors, single pole, double pole, 3 pole or three phase contactors, 4 pole contactors, high current contactors, NEMA contactors, Screw terminals, LVC or (Vacuum Contactor), DIN rail and mercury contactors.

Ac contactors have a wide range of ac and dc coil variants as mentioned previously, a wide range of auxiliary contacts, operating voltage, Versions with AC, AC/DC, or DC control.
