Carrier HN53HG120 Contactor

The Carrier HN53HG120 contactor is an electrically operated switch used for controlling HVAC applications. It operates by making and breaking circuits and controlling the amount of high current that flows between the source and the load. Contactors are commonly applied in HVAC equipment to control high-power loads like compressors, heaters and motors. By disconnecting the control circuit from the high-power circuit, contactors safeguard electrical parts from fluctuations and short circuits. Contactors are used to bear the load of the starting and stopping of high power loads which in turn relieves other more delicate loads and thereby increasing their life span.
