Product Description
Danfoss MP55A oil differential pressure switch, genuine OEM code number 060B029691. 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; automatic reset. SPDT contact system, M12x1.5 metric thread (ISO 8434-1) pressure connection, screwed cable entry (Pg 13.5), IP20 enclosure. Max. working pressure 17 bar. Suitable for HCFC and non-flammable HFC refrigerants. EAN 5702424499648.

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