Schneider Electric 9012-GBW-1 USNT Circuit Breaker

Schneider Electric Square D 9012GBW1 pressure switch is a diaphragm‑type industrial control device designed to provide reliable pressure‑actuated switching for hydraulic, pneumatic, and non‑corrosive liquids or gases. It uses SPDT (isolated) contacts rated up to 600 V and 10 A, with a 1/2 in NPT external pressure connection and a 1/4 in NPTF internal fluid connection. The unit features a Buna‑N diaphragm and a zinc‑plated steel flange, enclosed in a NEMA 4/4X/13 rated housing for indoor/outdoor use. It is UL Listed and CSA Certified as industrial control equipment, with conformity to IEC 60957.5.1 and CE; RoHS: No. The 9012GBW1 offers an adjustable differential of 16–90 PSIG and a decreasing‑pressure range of 13–425 PSIG, with a maximum allowable pressure of 850 PSIG. Ambient operating temperature is −23 to 85 °C (−10 to 185 °F) and media temperature ranges from −40 to 120 °C (−40 to 248 °F). Electrical connection is 1/2 in, 14 NPT; fluid connection 1/4 in 18 NPTF (internal). The device supports up to 120 operating cycles per minute, with repeat accuracy of ±0.1–1% of the range and drift of ±1% over 1 million cycles. Typical applications include controlling pumps, compressors, machine tools, hydraulic circuits, and other equipment requiring precise pressure actuation.
