Szczegóły produktu

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.
