GAZ080ET6 - 3P CHANGEOVER SWITCH 80A ENCLOSED

Why Choose the GAZ080ET6?

The Lovato GAZ080ET6 is a three‑pole line changeover switch I‑0‑II, rated 80 A, supplied in a UL/CSA Type 4/4X non‑metallic enclosure for demanding environments. The compact IP65 frontal protection and 280x220x172mm enclosure suit control panels and distribution boards. With Ui 1000 V and Uimp 8 kV, it delivers dependable isolation and supply selection for AC systems.

Designed for performance, it achieves AC21A and AC22A currents of 80 A up to 690 V, and AC23A of 80 A at 400 V, 63 A at 500 V, and 47 A at 690 V. Making/breaking at AC23A 400 V are 800 A/640 A. Conditional short‑circuit current is 50 kA with gG80 fuse. Mechanical and electrical life reach 30,000 cycles, with operation from −25 to +55 °C.
