Carrier HK02ZA442 Pressure Switch 448 PSI Open 327 PSI Close

The Carrier HK02ZA442 High-Pressure Switch is an essential safety switch meant for Carrier HVAC systems. This small but essential change is important in preventing your system from being damaged by pressure build up. When the pressure of the refrigerant goes high, the switch turns off the power supply to the compressor. It protects your system by having an in-built mechanism that turns off the compressor whenever refrigerant pressure is high, which is dangerous for the equipment. As a result of not allowing the compressor to run under unsafe conditions, high-pressure switch ensures efficient system operation and durability. Manufactured from high quality materials, the high pressure switch is designed for long term use within your HVAC system.
