Carrier HK02ZB041 Low Pressure Switch 44/27 PSI

The Carrier HK02ZB041 is a low-pressure switch for Carrier air conditioning and refrigeration equipment. This features two key pressure ratings, a pressure rating starts at 44 PSI and another pressure rating is near about 27 PSI. When the refrigerant pressure is less than the close pressure of 27 PSI, the switch breaks the electrical circuit. On the other hand, when the pressure goes higher than the open pressure of 44 PSI, the switch connects the circuit. Controlling the pressure of the refrigerants, also guards the Carrier HVAC system against pressure-related harms such as low pressure or high pressure.
