GAZM025ET6 - 3P 25A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM025ET6?

The Lovato GAZM025ET6 is a three‑pole line changeover switch (I‑0‑II) in a rugged IP65 metal enclosure, engineered for dependable AC service at 25 A. Compact yet robust, the enclosure measures 150 x 200 x 120 mm, making it easy to integrate into control panels. Designed for clear source selection and isolation, it supports reliable switching across demanding industrial environments.

Built to IEC/EN 60947‑3 and 60947‑1, it offers 1000 V Ui and 8 kV Uimp resilience, with 25 A ratings across AC21A, AC22A and AC23A duties at 400/500/690 V. Rated operational power reaches 11 kW at 400 V and 22 kW at 690 V. With 100000 mechanical and electrical cycles, IP65 protection, and operation from −25 to +55 °C up to 3000 m altitude, it delivers durable performance in switching and transfer applications.
