Pressure switch for 80-100 psi systems

The Square D 9013FH pressure switch controls air compressors in the 80 to 100 psi range. It uses a DPST contact form with standard action and a 20 psi differential. The switch includes an unloader valve and a single 1/4 inch FNPS port. It is rated for NEMA 1 enclosure protection.

Check voltage phase and motor rating

Verify that your compressor motor matches the listed horsepower ratings at your supply voltage. The switch supports 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. Confirm the port thread size and unloader compatibility before installation.

Steady cycling at 20 psi differential

Under sustained load the switch cycles between the 80 psi cut-in and 100 psi cut-out points with a fixed 20 psi differential. The unloader valve releases head pressure on each off cycle to reduce motor starting torque. NEMA 1 rating protects the contacts in typical indoor compressor environments.

Questions about this item

Does the 9013FH switch arrive with any fittings or do I need to buy a 1/4 in FNPS connector separately?

The switch includes a 1/4 in FNPS port and an unloader valve; no extra fittings are required for standard air-compressor plumbing.

How do I decide between the 80/100 psi setting and another range for my compressor?

This model is factory-set to cut in at 80 psi and cut out at 100 psi with a fixed 20 psi differential, so choose it when that exact band matches your tank rating.

Will the 2 hp rating at 120 V single-phase handle my 1.5 hp motor without tripping?

Yes, the contacts are rated 2 hp at 120 V single-phase, 3 hp at 240 V single-phase and 5 hp at 240 V three-phase, giving ample margin for a 1.5 hp motor.
