Description
The Supco SHP425300 High Pressure Switch is a control component used to sense refrigerant discharge pressure in cooling and circuits. It is calibrated with a 300 PSI cut-in and 425 PSI cut-out range enabling it to reset and respond at defined pressure thresholds during system operation. These parameters help manage control circuit switching based on pressure buildup in the refrigerant line. It is used in HVAC systems where pressure supervision is required to maintain controlled compressor cycling and support stable operation during load and ambient conditions.
