MP/MP-A, oil differential pressure controls
MP 54 and MP 55 oil differential pressure controls are used as sefety switches to protect refrigeration compressors against low lubricating oil pressure.
If the oil pressure fails the oil differential pressure control stops the compressor after a certain time period.
MP 54 differential pressure control, fixed differential, low differential pressure
