XMP Schneider®Electric series pressure switches

For power circuits, XMP type, IP 54 protection grade Calibre 6 bar (87psi).

Adjustable differential, for adjustment between 2 thresholds

Devices with one three-pole 3 “NC” contact


OPERATION

The XMP pressure switches are for power circuits, with adjustable differential. They are used for controlling water and air pressure, up to 25 bar.


DECOMPRESSION VALVE

Depending on the models, XMP pressure switches are equipped with 2 types of decompression valve:

  • straight decompression valve with quick coupling (connection on a Ø 6 mm plastic pipe).
  • straight decompression valve with compression fitting (connection on Ø 6 mm plastic or metal pipe).

REGULATION

XMP pressure switches are adjusted by first setting the high point and then the low point.

High point

The high point (rising pressure) is adjusted by means of the adjustment nut or wheel 1.

Tighten the nut or wheel 1 to increase the value of the high point.

Low point

The low point (dropping pressure) is adjusted by means of nut 2.

Tighten the nut 2to decrease the value of the low point (increasing differential).
