P30-5827 Robertshaw LUBE OIL CONTROL PRESSURE CONTROL

These lube oil protection controls guard pressure-lubricated refrigeration compressors against major damage due to loss of oil pressure. If adequate oil pressure is lost, the built-in P30 Time Delay Switch starts timing. If the oil pressure does not recover within the set period, the control circuit is opened, stopping the compressor. These controls also feature replaceable time delay modules, Super Cap® capillary protection system, front-located captive cover screw and adjustable pressure range (P30-3000 models only).
