Square D 9012GNG3 Pressure Switch 1-40 Psig Spdt

Product Description

The SQUARE D 9012GNG3 is an electromechanical pressure and level switch designed for industrial and commercial fluid control applications. It features a single-pole double-throw (SPDT) contact form with an adjustable pressure range of 1 to 40 psig, making it suitable for a wide range of system setpoints. The switch operates on 120 VAC, 240 VAC, 125 VDC, and 250 VDC circuits and is rated at 6 amps. Its screw terminal connections and 1/4-inch fluid connection port allow for straightforward field wiring and plumbing integration. The unit carries a NEMA 1 enclosure rating and meets multiple agency standards including UL 508, CSA C22.2 No. 14, and CE.

The 9012GNG3 is built for use in hydraulic and pneumatic systems where reliable pressure sensing and switching is required. Typical applications include compressor control, pump protection, and pressure monitoring in light industrial, mechanical room, and process equipment installations. The adjustable differential pressure range of 1.2 to 6 psi allows technicians to fine-tune the switch response to match system requirements. Its vibration-resistant construction makes it a practical choice for installations subject to mechanical vibration from pumps, compressors, or mobile equipment.
