Schneider Electric 9012 GCW-3 Pressure Switch

Schneider Electric's Square D 9012 GCW-3 Pressure Switch provides two adjustable switching thresholds over a 170–5600 psi range, enabling precise control of pumps and machinery in hydraulic and pneumatic systems. It uses a 1/4 in NPTF sensing port and a 1/2 in NPT conduit entrance for wiring, and carries a 480 VAC, 10 A electrical rating suitable for control circuits in industrial equipment. The GCW-3 variant carries the model designation G17H11V1Z18, ensuring the exact setpoint range and contact configuration associated with this configuration. As part of the 9012G family of industrial pressure switches, this device is designed to be wired into automation circuits to start and stop equipment when pressure crosses the defined thresholds, making it applicable for pump protection, compressor control, and other process equipment in manufacturing environments.
