OIL FAILURE CUTOUT; SAME AS P45NCB-12 W/ALARM CIRCUIT

The P45 controls provide dependable economical low lube oil pressure cutout for pressure lubricated refrigeration compressors. The factory set pressure adjustment provides operation to the compressor manufacturer's specification. The P45 control measures the net oil pressure available to circulate oil through the lubrication system. (Net oil pressure is the difference between the oil gage pressure and the refrigerant pressure in the crankcase.) A built-in time delay relay, compensated for ambient temperature, allows for pressure pickup on start and avoids nuisance shutdowns on short duration pressure losses during the running cycle.
