Square D 9012GAW22 Pressure Switch 1-40 Psig Dpdt

Product Description

The SQUARE D 9012GAW22 is an electromechanical pressure and level switch rated for 1 to 40 psig, designed for use in hydraulic and pneumatic control systems. It features a double-pole double-throw (DPDT) contact form with screw terminal wiring connections and supports multiple voltage ratings: 120 VAC, 240 VAC, 125 VDC, and 250 VDC. The adjustable differential pressure range spans 1.6 psi minimum to 8 psi maximum. Built to withstand demanding industrial environments, the switch carries NEMA 4, 4X, and 13 ratings, providing protection against dust, oil, and water ingress. Licensed electricians and industrial controls technicians are the typical installers for this device.

This pressure switch is suited for industrial and commercial applications where reliable pressure monitoring and switching is required in hydraulic or pneumatic systems. The NEMA 4X rating makes it appropriate for wet or corrosive environments where additional enclosure protection is needed. The adjustable differential pressure setting allows technicians to fine-tune switching points for a given system's operating requirements. Its vibration-resistant construction makes it a sound choice for installations near compressors, pumps, or other mechanical equipment that generates continuous vibration.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements and applicable local codes. Shut off and lock out all power and depressurize the system fully before connecting or disconnecting the switch. Use appropriate conduit fittings at the 1/2 inch conduit entry to maintain the enclosure's NEMA rating. Verify that system operating voltage matches one of the rated voltage configurations before energizing the circuit.
