Description
The Copeland 940-0001-51 Potential Relay Kit is an OEM-quality replacement component engineered for use with Copeland compressors. Potential relays play a critical role in single-phase compressor starting circuits — they sense the back-EMF (electromotive force) generated by the start winding and open the start capacitor circuit once the compressor motor reaches sufficient speed, protecting both the capacitor and the motor windings from overload.
