What is an HVAC contactor? An HVAC contactor is a switch used in HVAC systems such as air conditioners and heat pumps. It acts as an on/off switch to control power to the compressor and fan motors.
The main purposes of an HVAC contactor are:
- To start and stop the HVAC system. By opening or closing the contactor switch, it can power on or cut off power to the HVAC components like compressors and fans.
- To protect the HVAC components. The contactor acts as an overload protection device. If the current draw becomes too high, it will cut off power to prevent damage to the components.
- To reverse the direction of the current flow. In heat pumps, the contactor is used to reverse the flow of current through the compressor to switch between heating and cooling modes.
So, in summary, the HVAC contactor acts as a switch and overload protection device to control power to the heating and cooling components in the system according to the thermostat's commands.
