There are three color coded wire plugs redpositive blacknegative and blueneutral to match the terminals. 110 to 125vac solid state hardstart relay includes relay overload and start capacitor.

Supco Rco810
Rco810 wiring diagram. It reveals the elements of the circuit as simplified shapes as well as the power and signal links between the devices. A wiring diagram is a simplified conventional photographic depiction of an electric circuit. Prevents low voltage starting problems. Step 6 grasp the 3 n 1 relay box and locate the five wires protruding from it. Used refrigeration systems with or without run capacitors. Rated for 112 hp to 15 hp compressors.
Relatively easy to install helps if you can read a circuit diagram as you will be replacing 3 discreet components with 1 plugging the 3 wires with connectors onto the compressor and connecting the other 2 wires via marettes twist on wire connectors to the ac feed wires that previously were connected to the relay and overload protector. 110 to 125vac solid state hardstart relay includes relay overload and start capacitor. These are a universal set of relays you can use in place of the factory relays installed on your compressor. The diagram will display which terminals on the compressor have positive negative and neutral charges. Maximum rla 405 amps. Variety of supco 3 in 1 wiring diagram.
Used on refrigeration systems with or without run capacitors. This is a video showing you how to install a 3 in 1 start relay. You would want to use. Examine the wiring diagram on the compressor unit.
