Square D 9012GGW4 Pressure Switch 175 Psi Spdt-db Nema 4 4X

Product Description

The SQUARE D 9012GGW4 is an electromechanical pressure and level switch designed for industrial fluid control applications. It features a single-pole double-throw with double-break (SPDT-DB) contact form and is rated to 175 psi. The switch accepts multiple supply voltages, including 120 VAC, 240 VAC, 125 VDC, and 250 VDC, making it adaptable across a wide range of control circuits. Rated at 6 amps and built with vibration-resistant construction, it is suitable for demanding environments. A screw terminal connection simplifies field wiring, and the adjustable differential pressure setting allows technicians to dial in the switching point for the specific system.

This switch is rated for hydraulic and pneumatic systems and carries NEMA 4, 4X, and 13 enclosure ratings, making it appropriate for wet, dusty, and corrosive environments in both industrial and commercial installations. The fluid connection is 1/4 inch and the conduit entry is 1/2 inch, fitting standard trade fittings. Licensed electricians and industrial maintenance technicians typically install this switch in pump control panels, compressor circuits, and hydraulic power unit systems where reliable pressure-activated switching is required.

Compatibility

Designed for use with hydraulic systems and pneumatic systems as stated by the manufacturer. Verify system pressure range, voltage, and fluid media compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician or qualified industrial maintenance technician in accordance with the NEC and applicable local codes. De-energize the control panel and depressurize the system completely before connecting or disconnecting the switch. Use appropriately rated conduit fittings at the 1/2 inch conduit entry and ensure the fluid port connection is sealed and torqued per the system fitting requirements. Do not exceed the rated 175 psi or the rated amperage of 6 amps at the specified voltages.
