Pressure Switch 9012G

The Square D 9012G is an adjustable pressure switch designed for monitoring and controlling system pressure in industrial and commercial applications. It suits maintenance engineers and automation technicians who need reliable actuation across a broad pressure range.

NEMA 4 4X 13 Enclosure

The enclosure carries NEMA 4, 4X and 13 ratings, providing protection against windblown dust, rain, splashing water, hose-directed water and oil or coolant seepage. This allows installation in wash-down areas, outdoor panels or machine-tool environments without additional shielding.

3 to 180 PSI Adjustable Range

The switch operates on a 3 to 180 PSI range with a 6 to 30 PSI differential, actuated by a diaphragm mechanism. Buyers who need a wider differential or a higher maximum pressure will need a different device.

Questions about this item

How often should the diaphragm be inspected or replaced on the 9012G switch?

The diaphragm actuates the contacts; inspect it during routine system maintenance and replace if pressure response drifts outside the 6 to 30 psi differential range.

What contact rating limits continuous operation on a 120 V AC circuit?

The contacts are rated 6 A at 120 V AC; sustained loads above that will exceed the switch rating first.

How much heat does the switch generate when controlling a 6 A load at 120 V all day?

Contact dissipation at the rated 6 A, 120 V AC load is minimal; the NEMA 4/4X/13 enclosure handles normal operating temperature without additional cooling.
