Carrier 312926-252 High Pressure Switch 670-470 PSI

The Carrier 312926-252 High-Pressure Switch is an essentialsafety control equipment used in the HVAC systems to monitor and control the pressure of the refrigerant. This switch turns on when pressure is more than the safe operating range, it lowers pressure by turning down the compressor to prevent system damage. It operates between 470/670 volts. It is commonly found in home and industrial refrigerators, heat pumps and air conditioning systems. This switch is essential in any HVAC system since it provides system protection, improves operational safety and enhances the life of equipment through reduction of over-pressurization.
