The sensor is encapsulated in a rugged housing that protects the internal sensing element from moisture and vibration common in industrial and commercial HVACR environments

and small ventilating systems

minimizing the risk of thermal stress on high-limit switches or primary heat exchanger cells

offering reliable solenoid operation and consistent pressure regulation for natural gas HVAC systems

Copeland 971-0127-37 Relay R-22 The sensor is encapsulated inThe Copeland 971 0127 37 Relay is a critical motor protection component engineered for high performance HVACR compressor applications. This overload relay serves as the primary line of defense for the compressor motor, utilizing precise thermal sensing technology to interrupt the circuit when internal temperatures or current draw exceed safe operational limits. Designed for seamless integration with Copeland refrigeration parts, the 971 0127 37
