Copeland 940-0001-51 Potential Relay Kit

The Copeland 940-0001-51 Potential Relay Kit is a vital piece of the HVAC systems. This relay kit measures 3.5" long, 1.0" wide, and 2.2" high, operating at 60 Hz and accepting up to 375 volts.Its purpose is to control starting of compressor motors. The starting capacitor gets a improve from the potential relay so that compressor can begin its operation properly. Once the motor reaches certain rotational speed,coupling with high impedance reduces energy cost saving also increases compressors longevity. Therefore this relay kit is usually embedded in air conditioning/refrigeration system whose motor require reliable start up.
