What is auxiliary contactors?
In order to understand auxiliary contactor we first need to understand each of the terms specifically. The term auxiliary means helper and the term contactor refers to a mechanically operated switch which is used for switching an electric power circuit.
So basically these auxiliary switches act as a secondary switching device which works in connection with primary switching devices like relay, contactors and circuit breakers. They are also called as supplementary contacts or control contacts.
It has lower current rating but it has armature same as a power contactor. It acts as an additional motor starter. They are mainly used in devices where there is signal switching and defaults.
Both contactors and relays are electromagnetic switches and they both operate on the same working principle but with a basic difference that contactors operate in high rating current whereas a relay operates in low current rating.
