Boiler Low Water Cut-Off, the McDonnell & Miller PSE802M-24, delivers precise water level protection for boilers. This electronic probe-type device uses a 24V AC input and a rugged 7000 Ohm probe to promptly shut off flow when water runs low.
Designed for steam and water applications, it withstands demanding temperatures and pressures: storage -40 to 120°F, ambient 32 to 120°F, and water up to 250°F, with a pressure rating of 15 PSI steam and 160 PSI water. The unit includes a standard probe and a manual reset for reliable safety operation.
Built to code and ready for commercial and residential boiler rooms, it is UL listed (Canada and US) and ASME CSD-1 compliant, housed in a NEMA 1 enclosure for general purpose service.
