Water-pump pressure switch

The Square D 9013FY is a DPST pressure switch built for water-pump control. It opens and closes the circuit at factory-set points of 20 and 40 psi, handling up to 10 A. The switch suits residential and light-commercial pump systems that need reliable on-off operation.

Pressure range and electrical limits

The adjustable range spans 5 to 80 psi with a fixed differential of 20 to 30 psi. Single-phase ratings reach 2 hp at 120 V and 3 hp at 240 V, while three-phase ratings reach 5 hp at 240 V and 1 hp at 480 V. NEMA 1 enclosure restricts use to indoor or sheltered locations.

Build and connection details

A single 1/4 in FNPS port connects the pressure-sensing line, and the yellow finish aids visibility in utility areas. Operating temperature covers -22 to 257 degrees F. The switch has no unloader valve, so installers must plan for separate pressure relief if the system requires it.

Questions about this item

Should I pick the 20-40 psi model or a wider-range switch?

The 20-40 psi factory setting suits typical residential pumps; the switch can be adjusted across a 5-80 psi range with a 20-30 psi differential if your system needs different cut-in or cut-out points.

What does the 10 A rating mean when the motor is running?

The DPST contacts are rated for 10 A resistive load and can directly control single-phase motors up to 2 hp at 120 V or 3 hp at 240 V, plus three-phase motors up to 5 hp at 240 V or 1 hp at 480 V.

How does the 1/4 inch FNPS port connect to my pressure line?

The single 1/4 inch FNPS port accepts standard NPT pipe threads, so you can screw the switch straight onto a tee or nipple without extra adapters.
