Danfoss MP54 oil differential pressure switch, fixed differential, manual (minimum) reset, 120 s time delay, 1/4 in flare

Part Number
060B016991 · HS 9026.20

Danfoss MP54 oil differential pressure switch, genuine OEM code number 060B016991. 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. Fixed differential; manual (minimum) reset with a 120 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 5702424499792.

Compatibility

MP54 lube-oil protection control for reciprocating and scroll refrigeration/AC compressors. MP54 has a fixed differential (no setting disc). The 120 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.
