GAZM125ET6 - 3P 125A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM125ET6?

The Lovato GAZM125ET6 three‑pole I‑0‑II changeover switch in a robust IP65 metal enclosure delivers dependable source transfer for industrial and commercial power systems. Rated 125 A, it suits mains‑to‑generator applications and maintenance isolation. The compact 200×300×120 mm enclosure simplifies integration into panels or wall‑mounted assemblies while protecting against dust and water ingress, helping ensure continuity of supply and safe manual switching between two incoming lines.

Engineered for demanding duties, it offers Ui 1000 V and Uimp 8 kV, with AC21A 125 A up to 690 V. AC23A capability supports 125 A/55 kW at 400 V and 47 A/45 kW at 690 V. Durable construction provides 30,000 mechanical and electrical cycles, with a -25 to +55 °C operating range, pollution degree 3 and installation up to 3000 m, conforming to IEC/EN 60947-3 and 60947-1.
