Description
This is a BRAND NEW General Purpose Relay with a 208-240 volt coil. Replaces Supco Mars and Steveco part #s 90374 & 90-374. Note that the picture shows a 5 terminal relay and a 6 terminal relay. Both models are being produced and both work in the same way but we cannot guarantee which you will receive as we are not guaranteed to receive the same type each time we order.
Function:
Relays are switches that open and close circuits electrically. In most HVAC equipment a low voltage coil relay (24 vac) is energized in order to open or close a higher voltage (usually 120-240) circuit.
