MP55E
MP55E oil differential pressure switches are used as safety switches to protect refrigeration compressors against low lubricating oil pressure.
If the oil pressure fails the oil differential pressure control stops the compressor. MP55E for HCFC, HFC and HC refrigerants are equipped with gold-plated SPDT contacts, which react directly on the differential pressure without time delay.
The units are designed to operate in explosive zones acc. to 2014/34/EU, Atex directive, explosive zone 2, surface equipment, category 3.
MP55E are delivered with ¼ inch solder connections to ensure a hermetic installation.
