This assembly is optimized for Building Automation Systems (BAS) and commercial HVACR environments where HVAC valve control must remain consistent under high static pressures

The intake holes must face directly into the airflow

preventing common issues like soot accumulation or inconsistent burner flames

Trane RLY3148 Start Relay These figures represent the temperatureThe 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).
