Air-compressor pressure switch
The Square D 9013FH is a DPST pressure switch designed for single-port air-compressor systems. It provides automatic on/off control with an unloader valve for reduced motor load during start-up. Suitable for 120 V, 240 V and 480 V supplies in both single-phase and three-phase installations.
Factory set-points and range
The switch ships pre-set to cut in at 95 psi and cut out at 125 psi, giving a 30 psi differential. The adjustable range spans 40 psi to 150 psi, so the same unit can be recalibrated for other compressor pressure bands without changing hardware.
Motor-horsepower ratings
At 120 V single-phase the switch handles up to 1 1/2 hp, at 240 V single-phase up to 2 hp, at 240 V three-phase up to 3 hp, and at 480 V three-phase up to 1 hp. Builders whose motors exceed these ratings must select a different switch.

Questions about this item
Should I pick the 95-125 psi range or a wider 40-150 psi range for my compressor?
The 95-125 psi setting is factory-calibrated; the 40-150 psi span only shows the adjustment limits of the 9013FH series.
What does the 30 psi differential mean when the pump is running?
The compressor starts at 95 psi and stops at 125 psi, giving a 30 psi gap between cut-in and cut-out.
Will the 1/4 in FNPS port thread directly into my tank fitting?
Yes, the single 1/4 in FNPS port accepts standard 1/4 in NPT male fittings used on most small air tanks.
