Square D 9012GNG6 Pressure Switch 5-250 Psig Spdt

Product Description

The SQUARE D 9012GNG6 is an electromechanical pressure and level switch designed for industrial and commercial fluid-power applications. It operates across a range of 5 to 250 psig with a single-pole double-throw (SPDT) contact form, making it suitable for both monitoring and control duties. The switch supports multiple voltage ratings including 120 VAC, 240 VAC, 125 VDC, and 250 VDC, with a 6-amp contact rating. Differential pressure is user-adjustable, with a minimum differential of 7.4 psi and a maximum of 56 psi. Connections include a 1/4-inch fluid port and a 1/2-inch conduit entry with screw terminal wiring. The unit carries a NEMA 1 enclosure rating and is built with vibration-resistant construction.

The 9012GNG6 is intended for use in hydraulic and pneumatic systems where reliable pressure sensing and switching is required. Typical installations include compressor control circuits, hydraulic power unit interlocks, and pressure-monitoring loops in industrial machinery. The adjustable differential pressure setting allows technicians to tune the switch to specific system requirements without replacing the unit. The screw terminal connections and standard conduit entry simplify field wiring for both new installations and retrofit applications.

Installation Notes

Installation should be performed by a qualified electrician or instrumentation technician. De-energize the circuit and depressurize the system fully before connecting or disconnecting the switch. Conduit and wiring must comply with applicable NEC requirements for the installation environment. Verify the system fluid is compatible with the switch wetted materials before placing the unit in service.
