Square D 9012GAR5 Pressure Switch 3-150 Psig Nema 7 9

Product Description

The SQUARE D 9012GAR5 is an electromechanical pressure and level switch designed for industrial and commercial fluid-control applications. It operates across a pressure range of 3 to 150 psig with an adjustable differential, making it adaptable to a wide variety of system setpoints. The switch uses an SPDT-DB contact form with screw terminal connections and supports multiple voltage configurations: 120 VAC, 240 VAC, 125 VDC, and 250 VDC. Rated at 6 amps, it is built to NEMA 7 and NEMA 9 standards for use in hazardous locations. Licensed electricians and instrumentation technicians are the primary installers of this device.

This pressure switch is suited for hydraulic systems and pneumatic systems in both industrial and commercial environments. Its vibration-resistant construction makes it appropriate for installations where mechanical shock or continuous vibration is present, such as compressor skids, pump stations, or fluid-power panels. The 1/4-inch fluid connection port and 1/2-inch conduit connector accommodate standard piping and conduit configurations common in these applications. It is typically installed as a control or safety interlock device within pressure-sensing circuits.

Compatibility

Designed for use with hydraulic systems and pneumatic systems as stated by the manufacturer. Verify system pressure range and voltage requirements against your application before installation.

Installation Notes

Installation should be performed by a licensed electrician or qualified instrumentation technician in accordance with the NEC and any applicable local codes. De-energize the circuit and depressurize the connected system completely before making any fluid or electrical connections. The 1/2-inch conduit entry and screw terminals must be properly sealed and torqued per conduit fitting manufacturer specifications to maintain the NEMA 7 and NEMA 9 hazardous-location ratings. Do not exceed the rated pressure or amperage limits stated on the device nameplate.
