Square D 9013FH Pressure Switch 80-100 PSI
The Square D 9013FH pressure switch controls air compressor motors between 80 and 100 PSI with a 20 PSI differential. It features four 1/4-inch FNPS ports and an integrated unloader valve for standard compressor installations. The DPST contact form handles single-phase loads up to 1.5 HP at 120V or 2 HP at 240V, plus three-phase ratings of 3 HP at 240V and 1 HP at 480V.
Installers needing a direct replacement for 9013FH
This switch suits technicians maintaining existing compressor systems that specify the 80-100 PSI factory range and four-port unloader configuration. Buyers who require adjustable cut-in and cut-out pressures outside the fixed 20 PSI differential should look at adjustable-range models. Systems needing NEMA 4 or higher enclosure ratings for wash-down environments will need a different enclosure type.
Wiring uses standard DPST terminals
Installation involves connecting line and motor leads to the DPST contacts and plumbing the four ports with 1/4-inch fittings. The unloader valve ports must be piped to the compressor head unloader line for proper operation. Common issues include cross-threading the FNPS ports during assembly and forgetting to depressurise the tank before removing the old switch.

Questions about this item
What voltage and phase supply do I need for the 1½ hp rating on this 9013FH switch?
The 1½ hp rating applies to a single-phase 120 V supply; 2 hp at 240 V single-phase, 3 hp at 240 V three-phase and 1 hp at 480 V three-phase are also listed.
Will the ¼ in FNPS ports thread directly into the ¼ in compression fittings on my existing unloader line?
Yes, the four ports are ¼ in FNPS and the unloader connection is ¼ in compression, so standard ¼ in NPT fittings and compression tubing will mate without adapters.
How can I confirm the switch is cycling at the correct 80/100 psi after installation?
Watch the tank gauge: the compressor should cut in at 80 psi, run until 100 psi, then unload; the 20 psi differential is factory-set and not adjustable.
