Square D 9013FSG Pressure Switch with Low Pressure Cut‑Off

The Square D 9013FSG pressure switch is designed for reliable control and protection of electrically driven water pumps. This diaphragm‑actuated pressure switch includes a low pressure cut‑off (Auto Start‑Off), helping prevent pump damage caused by loss of pressure or dry‑run conditions.

The FSG series is a proven standard for water pump control and is suitable for jet pumps, submersible pumps, reciprocating pumps, and pressure booster systems. It features an adjustable pressure differential, allowing precise configuration to match system requirements.

For applications requiring additional safety or control, optional configurations such as a manual cut‑out lever (M1) and pulsation plugs are available upon request.
