  • Safety pressure switches for heating systems applications
  • The devices automatically stop the heat generator when a pre-set water pressure limit is drop off
  • Reset is exclusively manual by pressing the manual reset key after the pressure has returned by at least 0.4 bar within the shutoff value
  • External graduated scale on the instrument
  • Double normally open contact (LPR/5) in brass alloy with Ag-Ni coating
  • Terminals with M4 screws and 8×8 mm pressure dice
  • NBR rubber membrane with textile insert
  • ¼” F hydraulic connection made of galvanised steel
  • Standard protection degree IP 44
  • Tear resistant cable clamps
  • Maximum fl uid temperature: 110°C
  • Max ambient temperature 55°C
