Johnson Controls P28AA-1C Lube Oil Pressure Cut-Out Control

The Lube Oil Pressure Cut-Out Control from Johnson Controls, model P28AA-1C, is an adjustable safety device designed for commercial air conditioning and industrial refrigeration systems. This control protects lubrication circuits by triggering on precise oil pressure thresholds within an adjustable range of 8 to 70 PSI. With a 120 to 240 VAC contact rating and a 1/4 inch flare nut connection, it offers reliable, field-ready performance inside a NEMA 1 enclosure. Ideal for indoor equipment rooms, it features a 36 inch capillary and a 90-second time delay to minimize nuisance trips during startup and transients.
