LP/3
LOW PRESSURE SWITCH
Add safety to your system. In combination with the traditional pressure switch, this device allows to lock the pump when the water is missing. It can be easily applied to existing systems equipped with a single-phase electromechanical pressure switch.

Features
• Pressure switch for the protection of water systems (booster sets and fire-fighting 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 booster sets 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 higher than the start value again or when pressing the reset button.
• Double electric contact: normally open, made of brass alloy with Ag-Ni surfacing.
• NBR rubber nylon membrane.
• Tear resistant cable clamps.
Optionals – special arrangements
• Several available hydraulic connections.
• Customized settings.
• Version with electrical cables for motor and line connection.

Features
• Series of pressure switches for control applications and supervision in different technological systems (fire fighting units, building machineries, systems for water treatment, etc).
• The pressure switch mechanically works per action of the pressure in the system and it doesn’t need any additional electrical power supply.
• SPDT contact (single pole double throw COM.-N.O.-N.C.).
• Membrane in NBR rubber with textile insert.
• Tear resistant cable clamps.
