Description
The Carrier HN53HF212 is a 3-pole 60A contactor for 208-240V HVAC applications. A contactor is a relay that switches high currents to components such as compressors and heating elements. It works like a switch where it has a low voltage signal from the thermostat and then it makes or breaks the circuit to turn on or off the high-power equipment. Used in furnaces, air conditioners and heat pumps, contactors are safety devices that help to isolate the control circuits from the high power load.
