P29NC 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 PSIG (KPA) RANGE0 to 100 MAXIMUM AMBIENT TEMPERATURE F°(C°) 150 DIFFERENTIAL PSI (KPA)2 to 50 NEMA RATING1 OUTPUTSPDT Relay LIMITED WARRANTY YEARS1
