Pressure Switch 5-250 PSI

The Square D 9012G is an adjustable pressure switch with a 5 to 250 psi operating range and a 7.4 to 33.6 psi differential. It features a 1/4-18 NPT port, diaphragm actuation and a NEMA 1 enclosure rating. The switch provides one normally open and one normally closed contact for control circuits.

Industrial and HVAC Control

This switch suits installers needing a standard-action device for air, water or oil pressure monitoring within the stated temperature limits. It is not for buyers who require a different port size, a tighter fixed differential or a higher NEMA rating for outdoor or wash-down environments.

Electrical Ratings Included

The contacts are rated at 3 A at 240 V AC, 0.22 A at 125 V DC and 0.27 A at 250 V DC. These ratings determine the maximum pilot-duty load the switch can handle directly. No additional accessories or software are bundled with this unit.

Questions about this item

What piping thread does the 1/4-18 FNPT port on the 9012G pressure switch require?

The switch uses a 1/4-18 FNPT port; you must supply mating pipe or tubing with a matching male NPT thread and sealant.

Can the 9012G replace an older switch that was rated for 250 psi maximum?

Yes, the 9012G covers a 5 to 250 psi range, so it fits systems previously set at the 250 psi limit.

How do I verify the 9012G is actuating at the correct pressure after installation?

Pressurise the system and watch the gauge; the contacts should change state within the 7.4 to 33.6 psi differential band you have set.
