Inverse pressure switch LP/3

Low pressure switch

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 8x8 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
