Copeland 940-0001-79 Potential Relay Els PW 17895 this specific model is designed

this specific model is designed for chilled and hot water applications only

This SPDT relay features a multi-voltage coil that accepts 24VAC/DC

Designed to provide the initial electrical boost required to overcome head pressure

this switch prevents overheating by interrupting the 24V circuit to the gas valve when plenum temperatures exceed safety thresholds

this HVAC duct probe provides the stable resistance-temperature (R/T) characteristics necessary for reliable building automation inputs

Copeland 940-0001-79 Potential Relay Els PW 17895 this specific model is designedThe Copeland 940 0001 79 Potential Relay is a mission critical component designed for high torque motor starting in commercial refrigeration and air conditioning systems. Engineered for precision, this 3ARR3KC3P5 potential relay monitors the back electromotive force (EMF) to efficiently disconnect the start capacitor once the compressor reaches optimal operating speed. This OEM Copeland replacement part ensures consistent compressor start up and
