Square D 9012GFW2 Pressure Switch 90-2900 Psi Spdt Nema 4 4X

Product Description

The SQUARE D 9012GFW2 is an electromechanical pressure and level switch rated for 90 to 2,900 psi service. It uses a single-pole double-throw (SPDT) contact form with a fixed differential pressure design, meaning the operating differential is set at the factory and is not field-adjustable. The switch handles 120 VAC at 6 amps, 240 VAC at 3 amps, 125 VDC at 0.22 amps, and 250 VDC at 0.27 amps. Connections are made via a 0.25-inch screw terminal connector. Licensed electricians and industrial maintenance technicians are the primary installers for this type of switching device.

The 9012GFW2 is suited for industrial and commercial pressure monitoring applications where reliable switching across a wide pressure range is required. Its vibration-resistant construction makes it appropriate for use on compressors, pumps, hydraulic systems, and similar equipment subject to mechanical vibration. The enclosure carries NEMA 4, 4X, and 13 ratings, making it compatible with wet, washdown, and oil-mist environments. This switch is intended for use with the 9012G series mounting and pipe-connection hardware.

Key Features

• Wide pressure range: 90 to 2,900 psi operating range covers most industrial pump and compressor applications
• Fixed differential pressure: minimum differential 90 psig, maximum differential 170 psig — no field adjustment required
• SPDT contact form supports both normally open and normally closed circuit configurations
• NEMA 4, 4X, and 13 rated enclosure resists water ingress, corrosion, and oil mist
• Vibration-resistant design for use on compressors and rotating equipment
• Meets CE, CSA, UL 508, IEC, and RoHS requirements for broad compliance coverage

Compatibility

Designed for use with the 9012G series pressure switch accessories and pipe-connection fittings as specified by the manufacturer. No additional specific model compatibility data was provided in the product documentation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize the circuit and bleed system pressure to zero before removing or installing the switch. Use appropriate pipe thread sealant on the pressure port connection and verify the system pressure range does not exceed the 2,900 psi maximum rating before commissioning. The screw terminal connections should be torqued in accordance with the terminal manufacturer specifications found in the product instruction sheet.
