P29AC is a low pressure control with time delay and lockout, which requires manual reset. A drop in pressure energizes the time delay relay and opens a contact after the time delay, shutting down the equipment. The time delay prevents nuisance shutdowns due to momentary fluctuations in system pressures.Features: direct reading scale indicationdust-protected snap action switchtrip-free manual resetreplacement timing relays available Product Specifications BRANDJohnson Controls MAXIMUM OVERPRESSURE PSIG (KPA)1 (6.895) RANGE IN.
