Pressure switch for air compressors

The Square D 9013FH is a new pressure switch designed to control air compressors. It manages motor operation between factory-set cut-in and cut-out pressures of 95 and 125 psi. The unit features a standard action with a 30 psi differential and a 1/4 inch FNPS port connection.

Suits single-compressor systems needing DPST control

This switch fits installations requiring a DPST contact form and NEMA 1 rating within a 40 to 150 psi range. It supports motor loads up to 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. Buyers needing an integrated unloader valve or a different pressure span should look at other models.

Manual Auto/Off lever provides local override

The built-in manual switch action lets operators force the compressor off or return to automatic cycling without opening the enclosure. No unloader valve is included, so a separate bleed device is required if the application demands head-pressure release on shutdown. The switch operates reliably from -22 to 257 degrees F.

Questions about this item

What air compressor port size must I already have for the 1/4 in FNPS fitting on this 9013FH switch?

You need a compressor tank or line with a 1/4 inch FNPS threaded port to connect the single port on this pressure switch.

Will the 95-125 psi factory setting on this 9013FH switch still protect an older tank rated to 150 psi maximum?

Yes, the 125 psi cut-out stays below the 150 psi upper limit of the switch range, so the older tank remains within its rated pressure.

How can I confirm the 9013FH switch is cycling correctly after wiring it to a 2 hp 120 V motor?

Watch the pressure gauge: the compressor should start at 95 psi and stop at 125 psi, giving a 30 psi differential.
