Potential Relay

In air-conditioning installations, the potential (start) relay serves as a switch to disconnect the starting capacitors when the compressor motor has overcome the initial starting torque.

An important fact to remember is that each potential relay is specifically designed for the compressor to which it is attached. Should this relay fail or become erratic in its operation, no attempt should be made to repair it. The relay must be replaced with an identical component.
