Description
The Trane RLY03697 SPST Potential Start Relay is an electrical control component used to assist compressor startup during high-load operating conditions in HVAC systems. Designed for single-pole single-throw switching, this 50A relay responds to motor back electromotive force to disconnect the start capacitor once the compressor reaches operating speed. It is commonly placed in air conditioning condensers, rooftop units, and heat pump equipment where controlled compressor starting is required. Its role within the systems is an essential for working startup sequencing and maintaining consistent electrical performance.
