Square D 9013FH Pressure Switch
The Square D 9013FH is a four-port pressure switch designed for air-compressor control. It suits installers and maintenance teams who need a NEMA 1 rated switch with an integrated unloader valve for single- or three-phase motor circuits.
Factory-Set Range and Unloader
The switch arrives calibrated to open at 105 psi and close at 135 psi, delivering a 30 psi differential. Its built-in unloader valve bleeds head pressure on shutdown, reducing motor starting load and extending compressor life without extra plumbing.
Motor Ratings and Pressure Window
The DPST contacts handle 2 hp at 120 V single-phase, 3 hp at 240 V single-phase, 5 hp at 240 V three-phase and 1 hp at 480 V three-phase. The adjustable range spans 40 to 150 psi, so systems requiring cut-out pressures above 135 psi or differentials narrower than 30 psi will need a different model.

Questions about this item
Will the unloader valve on this 4-port pressure switch need periodic replacement?
The 1/4 in compression unloader is a mechanical part that can wear; keep a spare valve kit on hand for quick replacement when air leaks appear at the unload port.
What pressure limit stops the compressor first during continuous operation?
The factory cut-out is set at 135 psi; the switch opens at that pressure and will not allow the motor to run beyond it.
How much heat does the DPST contact block generate when the switch cycles all day?
With a 30 psi differential the contacts switch less often, keeping temperature rise low on the NEMA 1 enclosure during extended duty cycles.
