Square D 9012GDW1 Pressure Switch 0.2-10 Psi Spdt Nema 4 4X

Product Description

The SQUARE D 9012GDW1 is an electromechanical pressure and level switch designed for industrial and commercial control applications. It monitors system pressure and switches a single-pole double-throw (SPDT) output when pressure crosses the set point. The operating range spans 0.2 to 10 psi with a fixed differential, making it well suited for low-pressure sensing tasks such as air, gas, or liquid level control. Rated for 120 VAC at 6 amps and 240 VAC at 3 amps, it handles standard control-circuit voltages without an interposing relay. Licensed electricians and instrumentation technicians are the typical installers for this device.

This switch is intended for use with the 9012G series enclosure and control assemblies in residential, commercial, and light industrial settings. Its NEMA 4, 4X, and 13 ratings qualify it for indoor and outdoor installations where dust-tight and watertight protection are required, including washdown and corrosive-atmosphere environments. The screw-terminal, 0.25 inch connector interface simplifies field wiring. It is also rated for vibration-resistant service, suitable for installations on or near mechanical equipment with continuous vibration exposure.

Key Features

• Pressure range of 0.2 to 10 psi with fixed differential (minimum 0.2 psi, maximum 0.6 psi)
• SPDT contact form supports both normally open and normally closed control circuits
• NEMA 4, 4X, and 13 ratings for watertight, dust-tight, and corrosion-resistant enclosures
• Dual AC and DC ratings: 120 VAC at 6 amps, 240 VAC at 3 amps, 125 VDC at 0.22 amps, 250 VDC at 0.27 amps
• Vibration-resistant construction per IEC 68-2-6 for high-vibration environments
• RoHS compliant and UL Listed (File E12158, CCN NKPZ and CCN NTHT); also meets CSA and CE requirements

Compatibility

Designed for use with the 9012G series pressure switch assemblies as specified by the manufacturer.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. Disconnect and lock out all power to the control circuit before removing the existing switch or making wiring connections at the screw terminals. Verify that the supply voltage and load current fall within the rated values for AC or DC service before energizing. Confirm enclosure sealing and conduit entry integrity after installation to maintain the NEMA 4 and 4X rating.
