Differential oil pressure switch
The Danfoss MP54 differential pressure switch (part number 060B016891). Is an oil safety switch designed to to protect refrigeration and air conditioning compressors against low lubrication oil pressure.
Key Applications & Functions
- Compressor Protection: It monitors the pressure difference between the oil pump and the refrigerant suction pressure. If the oil pressure drops below a safe limit, the switch trips and safely shuts down the compressor to prevent mechanical failure.
- Integrated Time Delay: It features a built-in thermal time relay (often 45-60 seconds) that allows the system a brief grace period to build up oil pressure during startup before triggering an emergency shutdown.
- Industrial & Marine Use: It is commonly deployed in commercial HVAC units, freezers, and marine refrigeration systems.
- Refrigerant Compatibility: It is suitable for use with HCFC and non-flammable HFC refrigerants.
