GAZM080ET6 - 3P 80A CHANGEOVER METAL ENCLOSED SWITCH

Why Choose the GAZM080ET6?

Designed for reliable source selection, the Lovato GAZM080ET6 is a three‑pole I‑0‑II line changeover switch supplied in an IP65 metal enclosure. With Ith 80 A and AC operation, it delivers robust performance for transfer and isolation duties. The enclosure measures 200X300X120MM/7.9X11.8X4.7'', making panel integration straightforward while maintaining ingress protection for demanding industrial and building services environments.

Rated Ui 1000 V and Uimp 8 kV, it carries 80 A in AC21A/AC22A to 690 V, and up to 80 A (400 V), 63 A (500 V) or 47 A (690 V) in AC23A. With 50 kA conditional short-circuit current using gG80 fuses, 30,000-cycle mechanical and electrical life, IP65 protection, and IEC/EN 60947-3 compliance, it suits tough duties. Terminals accept 4–70 mm² conductors; torque 5–6 Nm.
