Square D 9012GDW5E3 Pressure Switch 3-150 Psig

Product Description

The SQUARE D 9012GDW5E3 is an electromechanical pressure and level switch rated for 3 to 150 psig, designed for use in hydraulic and pneumatic systems. It features a single-pole double-throw with double break (SPDT-DB) contact form and fixed differential pressure up to 6 psi. Voltage compatibility spans 120 VAC, 240 VAC, 125 VDC, and 250 VDC, with a 6-amp contact rating. The switch connects via a 1/4-inch fluid port and a 1/2-inch conduit entry, terminating at screw terminals. Licensed electricians and industrial maintenance technicians are the primary installers for this type of control device.

This switch is suited for industrial and commercial applications where reliable pressure sensing is required in hydraulic circuits or pneumatic control systems. Its vibration-resistant construction makes it appropriate for environments with mechanical movement or equipment-induced vibration. The NEMA 4, 4X, and 13 enclosure ratings allow installation in locations exposed to washdowns, dust, oil, and corrosive agents. It is a fixed-setpoint device, meaning no field adjustment of the differential is required during installation.

Key Features

• SPDT-DB contact form for reliable circuit switching in pressure-controlled applications
• Fixed differential pressure up to 6 psi for consistent, repeatable actuation
• NEMA 4, 4X, and 13 ratings provide protection against water, dust, oil, and corrosion
• Vibration-resistant design for use in mechanically active environments
• 1/4-inch fluid connection and 1/2-inch conduit entry with screw terminal wiring
• Multi-voltage compatibility: 120 VAC, 240 VAC, 125 VDC, and 250 VDC

Compatibility

Designed for use with hydraulic systems and pneumatic systems requiring electromechanical pressure or level switching within a 3 to 150 psig operating range.

Installation Notes

Installation should be performed by a licensed electrician or qualified industrial maintenance technician in accordance with the NEC and applicable local codes. De-energize the circuit and depressurize the system fully before connecting or disconnecting the switch. Use appropriately rated conduit and fittings at the 1/2-inch conduit entry to maintain the enclosure integrity rating. Do not exceed the rated voltage, amperage, or pressure range specified for this device.
