P29 Series: Low Pressure Cutout Control (With Time Delay)

Pressure P29 Series

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 60 seconds, shutting down the equipment. The time delay prevents nuisance shutdowns due to momentary fluctuations in system pressures.
