Pressure switch for air compressors

The Square D 9013FH pressure switch controls air compressors in light commercial or workshop settings. It manages motor start and stop cycles automatically between 120 psi cut-in and 150 psi cut-out. The unit suits single-phase or three-phase motors within the listed horsepower ratings.

1/4 in FNPS port with DPST contacts

A single 1/4 inch FNPS port connects directly to the compressor tank or line. Double-pole single-throw contacts switch both legs of the supply for safer motor isolation. NEMA 1 enclosure rating means the switch is intended for indoor, dry locations only. Manual Auto/Off lever allows local override without tools.

30 psi differential with no unloader valve

Factory differential is set at 30 psi across the 40 to 150 psi adjustable range. The switch draws up to 10 A through its contacts during motor starting. No built-in unloader valve is fitted, so a separate bleed arrangement is required to unload the compressor head on shutdown. Power ratings cover 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.

Questions about this item

What pressure range does the 9013FH switch cover and where does it cut out?

The switch operates from 40 to 150 psi with a 30 psi differential, so it cuts in at 120 psi and cuts out at 150 psi.

What port size and thread type does this switch need for mounting?

It has a single 1/4 inch FNPS port that threads directly into the compressor tank or manifold.

How is the 9013FH wired and what mistake do installers make?

Wire the DPST contacts to the motor circuit; a common error is forgetting that both poles must carry line voltage for the rated horsepower.
