Oil differential pressure switch P30

The oil differential pressure switch P30 is suitable for use on refrigeration compressors with external oil pump with refrigerants.

Its function is to protect the compressor from a lack of lubricating oil pressure, which could otherwise seriously damage the gears and cause compressor failure.

Connected to the crankcase and the oil pump via capillaries, the P30 pressure switch detects the difference between the pressure in the crankcase and the pressure on the outlet side of the oil pump.
