GE0800N - 3P SWITCH DISCONNECTOR W/NH FUSE HOLDER

Why Choose the GE0800N?

Designed for demanding AC installations, the Lovato GE0800N is a three‑pole switch disconnector with NH fuse holder rated at 800 A. With a robust GE product lineage and screw-on plate mounting, it delivers reliable isolation and protection. Rated insulation voltage Ui 1000 V and impulse withstand Uimp 12 kV provide confidence in harsh environments, while an IP20 frontal degree and pollution degree 3 support safer panel integration.

Engineered performance includes Ie up to 800 A in AC21A/AC22A at 400–500 V, and 630 A at 690 V; AC23A is 630 A at 400–500 V and 400 A at 690 V. Rated operational power reaches 355 kW at 400 V and 370 kW at 690 V. With 100 kA conditional short‑circuit rating, 5000 mechanical cycles, and operation from −25 to 55 °C up to 3000 m, it’s built for reliability.
