Ensure a proper ground reference is established via a metal tank wall or a dedicated common probe

It is rated for a Maximum Working Pressure (MWP) of 500 psig and a Maximum Operating Pressure Differential (MOPD) of 300 psig

an open-low action like the P100AC-2 is typically used as a low pressure cutout to prevent compressor operation during loss of charge or as a condenser fan cycling control to maintain head pressure

ensuring compliance with UL 555 and NFPA 90A standards

Utica-Dunkirk 550002258 Pressure Switch Els PW 17895 Ensure a proper ground referenceThe Utica Dunkirk 550002258 Pressure Switch is a critical safety component designed for precise combustion air monitoring in high efficiency gas furnaces and boilers. This SPDT air pressure switch is factory calibrated to a 0. 4" WC set point, ensuring the inducer motor generates sufficient static pressure before allowing the ignition sequence to proceed. It features a standard 1 4" barbed connection for secure pneumatic tubing attachment and provides
