Square D 9012GCW2 Pressure Level Switch 90-2900 Psig

Product Description

The SQUARE D 9012GCW2 is an electromechanical pressure and level switch rated for 90 to 2,900 psig, designed for demanding hydraulic and pneumatic system applications. It features a single-pole double-throw dead-band (SPDT-DB) contact form with screw terminal connections and adjustable differential pressure ranging from 170 to 560 psi. Voltage compatibility spans 120 VAC, 240 VAC, 125 VDC, and 250 VDC at a 6-amp rating. The switch carries NEMA 4, 4X, and 13 enclosure ratings, making it suitable for environments exposed to dust, oil, and water. Licensed electricians and industrial technicians are the primary installers of this switch in process control and equipment protection circuits.

The 9012GCW2 is used in residential and commercial hydraulic power units, pneumatic control systems, and industrial machine circuits where reliable pressure monitoring and switching is required. The fluid connection is 1/4 inch and the conduit connection is 1/2 inch, fitting standard plumbing and conduit configurations common in mechanical rooms and equipment panels. Its vibration-resistant construction makes it well suited for installations on pumps, compressors, and mobile equipment subject to continuous mechanical vibration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize the circuit and relieve system pressure fully before removing or installing the switch. The 1/4-inch fluid port connection should be made with appropriate thread sealant rated for the system fluid and pressure. Verify that the supply voltage and amperage match the switch ratings before restoring power.
