GAZM160ET6 - 3P 160A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM160ET6?

Engineered for reliable source transfer, the Lovato GAZM160ET6 three-pole line changeover switch delivers secure I-0-II selection in a robust IP65 metal enclosure. Rated Ith 160 A with AC operation, it offers 1000 V Ui and 8 kV Uimp resilience. Compact at 200x300x120mm, it suits demanding environments and control panels, supporting dependable mains/backup switching and distribution duties.

Performance spans duty categories: AC21A to 160 A up to 690 V, AC22A to 160 A at 400 V, and AC23A to 125 A at 400 V with 55 kW power. With 50 kA conditional short-circuit using gG160 fusing and IP65 frontal sealing, it meets IEC/EN 60947-3/-1. Terminals take 4–70 mm² at 5–6 Nm; operation −25 to +55 °C, to 3000 m.
