This high-performance Potential Relay is a critical electrical component designed for single-phase motor starting applications in HVAC systems. Operating as a Single Pole, Normally Closed (SP N.C.) switch, it effectively manages the transition of the start capacitor during the compressor's startup cycle. By sensing the back electromotive force (EMF), this relay ensures the start winding is disconnected at the precise voltage threshold of 132-148 volts, protecting the motor from overheating and extending the lifespan of the compressor. Ideal for air conditioning units and heat pumps, this replacement relay restores reliable starting performance and efficiency to residential and commercial cooling equipment.
Type: Electrical Start Relay
Size: Compact standard electrical housing
Application: Used primarily in HVAC systems, including central air conditioners and heat pump compressors, to facilitate reliable motor starting by managing capacitor circuits.
Specifications: Configuration: Single Pole Normally Closed (SP N.C.); Pick-up Voltage Range: 132-148 Volts; Function: Motor Start Potential Relay.
