- Pressure switch for the protection of water systems (autoclave and fi re-fi ghting systems) and pneumatic systems (control circuits under pressure)
- The device interrupts the electric connection between the line and the load when the pressure decreases below the established value (stop pressure)
- In the autoclave systems it is matched in series with a PM/5 pressure switch in order to protect the electric pump from dry running
- The reset is automatic when the pressure becomes again higher than the start value or when pressing the reset button
- Double electric contact: normally open, made of brass alloy with Ag-Ni surfacing
- Terminals with M4 screws and 8×8 mm pressure dice
- NBR rubber membrane with food grade textile insert
- ¼” F hydraulic connection made of galvanised steel
- Standard protection degree IP 44
- Max ambient temperature: 55°C
- Tear resistant cable clamps
Warning!
The pressure of the watercolum within the pipes cannot be greater than the stop pressure.
