- 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
