Square D 9012GBW2 Pressure Switch 20-675 Psig Spdt-db

Product Description

The SQUARE D 9012GBW2 is an electromechanical pressure and level switch rated for 20 to 675 psig, designed for use in hydraulic and pneumatic systems. It features a single-pole double-throw with double-break (SPDT-DB) contact form with screw terminal connections. The switch carries NEMA 4, 13, and 4X ratings, making it suitable for environments exposed to dust, oil, and washdown conditions. Rated at 6 amps across 120 VAC, 240 VAC, 125 VDC, and 250 VDC power sources, it delivers reliable electromechanical control across a wide range of industrial and commercial applications. A licensed electrician or controls technician typically installs this switch as part of a pressure-controlled circuit.

This switch is built for hydraulic and pneumatic system integration where adjustable differential pressure settings are required. The adjustable differential ranges from 27 psi minimum to 130 psi maximum, giving technicians flexibility during commissioning. The 1/4-inch fluid connection port fits standard hydraulic and pneumatic line fittings, while the 1/2-inch conduit connector accommodates typical conduit runs in panel and field installations. Its vibration-resistant construction makes it well suited for compressor rooms, pump skids, and industrial machinery where mechanical vibration is a factor.

Key Features

• SPDT-DB contact form with screw terminal wiring for secure, reliable connections
• Operating range of 20 to 675 psig with adjustable differential pressure (27 to 130 psi)
• NEMA 4, 13, and 4X enclosure ratings for oil-tight and corrosion-resistant protection
• Rated for 120 VAC, 240 VAC, 125 VDC, and 250 VDC at 6 amps
• Vibration-resistant design for use on compressors, pumps, and similar equipment
• 1/4-inch fluid connection and 1/2-inch conduit entry for straightforward field installation

Compatibility

Designed for use with hydraulic systems and pneumatic systems requiring electromechanical pressure switching within the 20 to 675 psig range.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements and applicable local codes. De-energize the circuit and depressurize the fluid system completely before connecting or disconnecting the switch. Verify that line voltage and current draw are within the rated values before closing the circuit. Use appropriate conduit fittings at the 1/2-inch conduit entry to maintain the NEMA enclosure rating after installation.
