Contactors & Auxiliary Contacts

What are Auxiliary Contacts?

Contactors and auxiliary contacts are pivotal elements in the domain of electrical control systems, ensuring the smooth operation and management of electrical circuits. A contactor is an electrically controlled switch utilised for switching an electrical circuit, similar to a relay but with higher current ratings. Auxiliary contacts, on the other hand, are additional contacts attached to the main contactor to provide feedback to control systems, indicating the status of the primary contacts. These components are indispensable in industrial and commercial applications, where they play a crucial role in maintaining and protecting electrical equipment.
