Pressure switch for air compressors

The Square D 9013FH pressure switch controls motor-driven air compressors in the 95 to 125 psi range. It suits single-phase and three-phase installations rated from 1 hp to 3 hp depending on voltage. The DPST contact form and standard action make it a direct replacement for compatible compressor pressure controls.

Check voltage phase and port thread before ordering

Verify that your compressor motor matches the listed horsepower ratings at 120 V, 240 V or 480 V. Confirm the unloader port uses a 1/4 in FNPS thread and that the system operates within the 40 to 150 psi adjustable range. The NEMA 1 rating limits use to indoor, dry locations only.

DPST contacts and unloader valve simplify daily

The double-pole single-throw contacts break both lines for safer motor disconnection. An integrated unloader valve bleeds head pressure on shutdown, reducing restart load on the motor. Factory settings of 95 psi cut-in and 125 psi cut-out with a 30 psi differential cover typical shop air demands without field adjustment.
