Johnson Controls P545NCB-82 Electronic Lube Oil Control Overview
The Johnson Controls P545NCB-82 is a precision-engineered Electronic Lube Oil Control designed to protect compressors from the damaging effects of low oil pressure. With a built-in 120-second time delay and a 7 PSI ± 1 PSID differential pressure setpoint, this control ensures reliable, accurate monitoring of lube oil pressure in commercial refrigeration and HVAC systems. The manual reset function with integrated alarm output provides a clear fault indication, while the dedicated liquid line solenoid output enables automatic system shutdown when unsafe conditions are detected. Rated for both 120 VAC and 240 VAC operation, the P545NCB-82 offers versatile installation compatibility across a wide range of equipment. Designed exclusively for use with non-corrosive refrigerants.
