Description
The Carrier HK02ZA439 is a pressure switch that protects and enhances Carrier HVAC systems. Inside a sensor is provided to measure pressure in the system. The switch activates an electrical circuit interruption when the pressure gets to the open threshold of 448 PSI. On the other hand, a pressure drop to 327 PSI causes the switch to close the circuit again. This on-off action assists in keeping safe and efficient operation throughout the engine. The 48″ lead makes it easy to install and it can easily be incorporated into different Carrier HVAC equipment.
