Product Description
Danfoss MP55 oil differential pressure switch, genuine OEM code number 060B017891. Protects a refrigeration or air-conditioning compressor against loss of lubricating oil pressure by monitoring the differential between oil-pump pressure and crankcase (suction) pressure and cutting out when it falls below the set value. Adjustable differential 0.3 bar–4.5 bar via the setting disc, factory set 0.65 bar, with readable internal scale; manual (minimum) reset with a 60 s time-delay relay that allows oil pressure to build during start-up. SPDT contact system, 1/4 in flare (DIN 8906) pressure connection, screwed cable entry (Pg 13.5), IP20 enclosure. Max. working pressure 17 bar. Suitable for HCFC and non-flammable HFC refrigerants. EAN 5702424499709.

Compatibility & Fitment
MP55 lube-oil protection control for reciprocating and scroll refrigeration/AC compressors. MP55/MP55A differential is adjustable via the setting disc. The 60 s variant is distinct from the other MP time-delay/reset options — verify the required time delay and reset (manual vs automatic) for the compressor.
