Schneider Electric 9012 GJW-21 Pressure Switch

Schneider Electric’s Square D 9012GJW21 pressure switch is a DPDT, four‑circuit industrial pressure switch in the 9012 family, designed to control equipment such as pumps and compressors via multiple switching outputs. It is rated for 480 VAC operation and offers an adjustable differential across a pressure range of 15 to 825 PSIG, making it suitable for applications that require precise start/stop control. The model’s operating setpoints are factory‑marked on the housing and can be readjusted according to Schneider Electric’s documented procedures. In industrial and machine‑tool contexts, the 9012GJW21 variant provides reliable multi‑point pressure control for systems that demand robust electrical interlocks and repeatable switching performance.
