Schneider Electric 9012ACW-5 Pressure Switch

Schneider Electric’s Square D 9012ACW-5 pressure switch is an industrial-class control device (Class 9012, Type ACW-5) used to automate electrical circuits in pressure‑controlled systems. It provides a pressure operating range of 1–75 psi with a differential of 4–15 psi, enabling equipment to start and stop at defined setpoints. Listed in Series B configurations, the 9012ACW-5 is widely sold under the Square D/Schneider Electric brand by distributors as 9012ACW-5 (and related part numbers). The unit supports voltages up to 600 V, making it suitable for medium‑ to high‑voltage control circuits in industrial environments. As part of the long‑standing 9012 family, this model delivers reliable, repeatable pressure‑triggered switching for pumps, compressors, or other pressure‑dependent equipment.
