Square D 9016GAW21 Pressure Switch Dpdt Nema 4 4X 13

Product Description

The SQUARE D 9016GAW21 is an electromechanical pressure and level switch designed for demanding industrial and commercial fluid-handling applications. It features a double-pole, double-throw (DPDT) contact form and operates at up to 480 VAC. The switch provides an adjustable differential pressure setting with a rated vacuum range reaching 28.3 inHg. Built with shock-resistant construction and rated to NEMA 4, 4X, and 13 enclosure standards, this switch is suited for environments where moisture, dust, and corrosion resistance are required. Licensed HVAC technicians, industrial electricians, and fluid-systems mechanics are the typical installers.

The 9016GAW21 is intended for use in hydraulic and pneumatic systems where reliable pressure sensing and switching is critical. It accepts a 1/2-14 electrical connection and a 1/4-18 inch fluid connection, making it compatible with standard pipe thread fittings common in both hydraulic circuit assemblies and pneumatic control panels. Its NEMA 4X rating makes it appropriate for wet or wash-down environments. Applications span light industrial machinery, process equipment, and fluid power systems requiring precise electromechanical control.

Key Features

• DPDT contact form supports both normally open and normally closed circuit configurations in a single device
• Adjustable differential pressure setting allows field calibration to system requirements
• NEMA 4, 4X, and 13 ratings provide protection against dust, oil, and water ingress
• Shock-resistant construction withstands vibration in hydraulic and pneumatic machinery
• 480 VAC rating covers most single-phase and three-phase industrial control circuit voltages
• Certified to UL File E12443, CSA File LR25490, and CE Marked for broad compliance

Compatibility

Designed for use with hydraulic systems and pneumatic systems as stated by the manufacturer. Specific compatible equipment models were not provided in the available product data.

Installation Notes

Installation should be performed by a qualified industrial electrician or fluid-systems technician familiar with pressure switch wiring and pipe thread connections. De-energize all circuits and depressurize the hydraulic or pneumatic line before making connections. Electrical connections should comply with the NEC and any applicable local codes. Verify differential pressure setpoint after installation before returning the system to service.
