GAZM080ET8 - 4P 80A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM080ET8?

Designed for dependable source selection, the Lovato GAZM080ET8 four‑pole line changeover switch (I‑0‑II) comes factory‑mounted in a robust IP65 metal enclosure. With an Ith of 80 A and AC operation, it delivers reliable isolation and switching for demanding installations. The enclosure measures 300x400x120mm (11.8x15.8x4.7''), offering ample space for connections while protecting the mechanism against dust and water ingress.

Engineered to IEC/EN 60947-3 and 60947-1, this GAZM unit offers 1000 V Ui and 8 kV Uimp, with AC21A/AC22A currents to 80 A across 400–690 V. For AC23A, it supports 80 A at 400 V, 63 A at 500 V, and 47 A at 690 V. Durable by design, it achieves 30,000 mechanical and electrical cycles, operates from -25 to +55 °C, and suits sites up to 3000 m.
