Description
The Trane SWT03017 SPST High Pressure Switch is a safety control system designed to monitor refrigerant discharge levels within equipment. It is calibrated to open at 650 PSIG, interrupting electrical control signals when system pressure exceeds the set limit within the HVAC systems. This action protects compressors, and related components from abnormal operating conditions caused by airflow restrictions, overcharging, or condenser issues. It is installed on the high-pressure side of air conditioning or heat pump units where it continuously monitors operating limits during compressor cycles. It plays an essential role in safeguarding refrigeration circuits in residential and commercial systems.
