Trane RLY3148 Start Relay it indicates a thermal eventThe Trane RLY3148 Start Relay is a high capacity potential relay engineered for heavy duty HVAC applications. Rated for 383V and 50A, this single phase component is critical for managing the initial inrush current during compressor start up. By temporarily engaging the start winding and disengaging once the motor reaches sufficient back EMF, it protects the compressor from electrical stress and reduces the risk of locked rotor amps (LRA).
