Description
The Trane RLY03690 Current Relay is an electromechanical switching component used to control compressor start circuits based on current sensing. It operates by detecting inrush current from the compressor motor and closing its internal contacts to the start winding as required during startup in HVAC systems. It operates at a current is reached to allow stable running conditions. Installed in air conditioning and heat pump units, it supports compressor start-up reduces electrical components, and ensures coordinated operation within residential and light commercial equipment.
