Carrier 00PPG000492100A Pressure Switch 160 PSI In 204 PSI Out

The Carrier 00PPG000492100A is a pressure switch designed for HVAC systems. This monitoring of the system pressure, preferably the refrigerant pressure, is useful as a safety mechanism. There are two settings on the switch a cut-out point 204 psi, and a cut-in point, which in this case is 160 psi. It turns ON the system when the pressure arrives the cut-in point and OFF when the pressure arrives the cut-out point. This prevents pressure build up on the parts inside the HVAC system and at the same time ensures that it will operate in a efficient manner.
