LP / 3LOW PRESSURE SWITCH

● Pressure switch for the protection of water systems(autoclave and fi re-fi ghting systems) and pneumaticsystems (control circuits under pressure)

● The device interrupts the electric connection betweenthe line and the load when the pressure decreasesbelow the established value (stop pressure)

● In the autoclave systems it is matched in series with aPM/5 pressure switch in order to protect the electricpump from dry running

● The reset is automatic when the pressure becomesagain higher than the start value or when pressing thereset button

● Double electric contact: normally open, made of brassalloy 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

APPLICATIONS: Pressure switches for water pumps, Dryrunning protecion
