Contactor Insights

What is Contactor?

A contactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current rating. Contactors are typically used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads. They are commonly used in applications where remote control, automation, or frequent switching is required. Contactors are rated by their operating current, voltage, and horsepower (or kilowatt) capacity.
