P29 Series Low Pressure Control with Time Delay Description 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. Refer to the P29 Series Low Pressure Cutout Control with Time Delay Relay Product Bulletin (LIT-125425) for important product application information. Features • direct reading scale indication • dust-protected snap action switch • trip-free manual reset • replacement timing relays available Applications • chiller low temperature • industrial equipment, oil pressure lubrication • low suction pressure P29 Series Low Pressure Control with Time Delay technical specifications • pilot duty rating of 750 VA, 120/240 VAC • external step down transformer for 440 and 550 VAC applications must be of sufficient capacity to supply 15 VA at 120 VAC or 30 VA at 240 VAC for time delay Accessories • universal mounting bracket (271-51) • replacement timing relays (Refer to Replacement Timing Relays for P28 and P29 Lube Oil Controls Catalog Page [LIT-1927395].) 127
