Square D 9012GCW3 Pressure Level Switch 170-5600 Psig

Product Description

The SQUARE D 9012GCW3 is an electromechanical pressure and level switch designed for industrial hydraulic and pneumatic system control. Rated for 170 to 5,600 psig operating range, it uses a single-pole double-throw with double break (SPDT-DB) contact form and accepts a screw terminal wiring connection. The switch supports multiple voltage inputs including 120 VAC, 240 VAC, 125 VDC, and 250 VDC, with a 6-amp contact rating. Built for demanding environments, it carries NEMA 4, 4X, and 13 enclosure ratings and is vibration-resistant per IEC standards. Licensed HVAC techs, instrumentation technicians, and industrial electricians typically specify and install this switch.

The 9012GCW3 is intended for use in hydraulic and pneumatic system applications where reliable pressure sensing and switching are required. The adjustable differential pressure range spans from 289 psi minimum to 1,260 psi maximum differential, giving installers flexibility to tune setpoints to system requirements. The 1/4-inch fluid connection port fits standard hydraulic and pneumatic line fittings, while the 1/2-inch conduit connector accommodates standard electrical conduit runs. This switch suits both industrial process control and mechanical system protection scenarios.

Installation Notes

Installation should be performed by a qualified electrician or instrumentation technician familiar with industrial control wiring and applicable NEC requirements. De-energize the circuit and depressurize the connected hydraulic or pneumatic line fully before connecting or removing the switch. The 1/4-inch fluid port should be connected with appropriate thread sealant rated for the system fluid and pressure. Conduit connections at the 1/2-inch entry point must be sealed appropriately to maintain the NEMA 4 and 4X enclosure rating.
