GAZ080ET8 - 4P CHANGEOVER SWITCH 80A ENCLOSED

Why Choose the GAZ080ET8?

The Lovato GAZ080ET8 is a four-pole line changeover switch I-0-II supplied in a robust UL/CSA Type 4/4X non-metallic enclosure. Rated Ith 80 A with Ui 1000 V and Uimp 8 kV, it delivers dependable manual source selection. The compact IP65 housing measures 280x220x172 mm, making installation straightforward in industrial and commercial switchboards.

Suited to demanding duties, it carries 80 A across AC21A and AC22A up to 690 V, and AC23A ratings of 80/63/47 A at 400/500/690 V. With 800 A making and 640 A breaking at 400 V, plus 50 kA conditional short-circuit withstand, reliability is built in. A 30,000-cycle mechanical and electrical life, 5–6 Nm terminals and 4–70 mm² conductors support durable, compliant installations.
