Copeland 940-0140-08 Potential Relay Els PW 17895 1% accuracyThe Copeland 940 0140 08 Potential Relay is a critical OEM compressor start component designed to manage the start up cycle of high torque single phase motors. Operating at a nominal 290 VAC rating, this relay leverages the back EMF generated by the motor's start winding to precisely time the removal of the start capacitor from the circuit. With a calibrated pick up voltage range of 340 360 VAC and a drop out voltage of 50 100 VAC, it ensures the
