Air-compressor pressure switch
The Square D 9013FH is a factory-set pressure switch for single-port air-compressor systems. It opens at 100 psi and closes at 70 psi with a fixed 30 psi differential. The unit carries a NEMA 1 rating and uses a DPST contact form for standard on/off action.
Sustained-load behaviour
Under continuous cycling the switch maintains the 70–100 psi band without drift. The DPST contacts are rated for 1½ hp at 120 V single-phase, 2 hp at 240 V single-phase, 3 hp at 240 V three-phase and 1 hp at 480 V three-phase. The unloader port vents line pressure each cycle to reduce motor restart torque.
Pre-installation checks
Verify that the compressor tank accepts a 1/4 in MNPT connection and that system pressure never exceeds 150 psi. Confirm the motor voltage and phase match one of the listed horsepower ratings. Ensure the mounting location satisfies the NEMA 1 indoor enclosure requirement.

Questions about this item
How much power does the 9013FH draw when the compressor runs all day?
The switch itself consumes negligible power; it simply carries up to 1 1/2 hp at 120 V or 2 hp at 240 V single-phase.
What fittings and wiring must I already have to install this pressure switch?
You need a 1/4 in MNPT port connection and wiring rated for the motor voltage you use — 120 V, 240 V or 480 V.
Will the 9013FH work with my older compressor motor rated for 3 hp at 240 V three-phase?
Yes, the switch is rated for 3 hp at 240 V three-phase, matching that motor.
