1/4" MP 54 Pressure Switch

MP 54 oil differential pressurecontrol is used as safety switchesto protect refrigeration compressors againstlow lubricating oil pressure.

If the oil pressure fails, the control will stop the compressor after a predetermined time period has elapsed.

MP 54 is used in refrigerating systems using HCFC and non-flammable HFC refrigerants.

MP 54 has a fixed differential pressure setting. It also incorporates a thermal time relay with a fixed release time setting.
