Everything about Contactor

High-rating electrical circuit switch

A contactor is a type of relay with high power rating. Contactors usually refer to devices switching more than 15 amperes or in circuits rated more than a few kilowatts. Contactors are typically used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads. The physical size of contactors ranges from a device small enough to pick up with one hand, to large devices approximately a meter on a side. Wikipedia →
