Description
The Carrier HK02ZB126 is a pressure switch that applies to different Carrier HVAC systems. It serves as a safety guard because it measures the pressure of the system and switches the signal on or off depending on the set levels. Usually, it will make the circuit close when the pressure gets below 126 PSI and will open the circuit when the pressure goes above 257 PSI. This has the function of controlling the pressure in each desirable operating range and also preventing damage to components due to abnormal pressure. These pressure switches are widely used in air handling systems, furnaces, and other HVAC equipment containing pressure-sensitive parts.
