PRES CONTROL W/TIME DELAY; 20"/100#; 120 SEC TIME DELAY; 36" CAP

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.
