A.J. Antunes 803112802 High Gas Pressure Switch Auto Reset 5-28" WC RHGP-A

The A.J. Antunes 803112802 High Gas Pressure Switch is used to protect HVAC systems including furnaces and boilers. This switch operates in a 5-28” WC pressure range and has an auto-reset feature once it has been tripped. It operates through the pressure of the gas; if the pressure rises beyond the limit, then the switch isolates the gas to avoid harm. This automatic reset feature makes it possible to restore service as soon as the pressure is back to normal.
