Pressure switch for air and water systems

This Square D 9013GH switch controls compressors and pumps in light-duty commercial and residential installations. It is rated for a 145 to 175 psi operating range with a 24 to 45 psi differential. The DPST contact form handles up to 10 amperes across single- and three-phase circuits. NEMA 1 enclosure suits indoor, dry locations.

3/8-inch FNPS port and standard action

A single 3/8-inch female pipe thread port connects directly to common tank or line fittings without adapters. Standard action opens contacts on pressure rise and closes on fall, giving predictable cut-in and cut-out behaviour. No unloader valve is fitted, so the installer must provide external unloading if the motor requires it. Factory settings are fixed at 145 and 175 psi.

Replaces worn electromechanical switches

The unit replaces failed or ageing pressure switches on existing air compressors and water pumps within the 32 to 250 psi range. It suits motors up to 2 hp at 120 V single-phase, 3 hp at 240 V single-phase, and 5 hp at 240 V or 480 V three-phase. Builders needing adjustable cut-in or cut-out points, an integrated unloader, or a higher NEMA rating should select a different model.

Questions about this item

What pressure range does the 9013GH switch cover and where are the on/off points set?

The switch operates from 32 to 250 psi with factory on/off settings at 145 psi cut-in and 175 psi cut-out.

What port size and thread type does the switch use for mounting?

It has a single 3/8 inch FNPS port for direct connection to the air or water line.

How is the 9013GH wired and what common mistake should be avoided?

Wire the DPST contacts to match the motor voltage — 120 V single-phase up to 2 hp, 240 V single-phase up to 3 hp, or 240/480 V three-phase up to 5 hp — and do not confuse the two pole pairs.
