Pressure Switch 40/20 psi DPST 10A

The Square D 9013GS is a water and air pressure switch designed for air compressor and water pump control. It uses a DPST contact form rated at 10A with a factory on/off setting of 40/20 psi. The switch operates on a reverse action principle with a pressure differential range of 15 to 30 psi. It carries a NEMA 1 rating for indoor use.

Single 1/4 in FNPS Port Compatibility

Before ordering verify that your system uses a single 1/4 in FNPS connection for the pressure port. Confirm the operating pressure falls within the 5 to 80 psi range and that the 15 to 30 psi differential suits your pump cycle requirements. Ensure the electrical supply matches the motor horsepower ratings listed for single or three-phase voltages. The switch has no unloader valve so external unloading must be handled separately.

Manual Switch Action and NEMA 1 Rating

The switch features manual switch action with no automatic unloader function included. Its NEMA 1 enclosure rating limits installation to dry indoor locations protected from dust and moisture. The DPST contact form allows simultaneous disconnection of both lines for motor loads up to 2 hp at 120V single phase, 3 hp at 240V single phase, and 5 hp at 240V or 480V three phase. No additional accessories or software are bundled with this unit.
