GE0250E - 3P CHANGEOVER SWITCH

Why Choose the GE0250E?

Designed for dependable source transfer, the Lovato GE0250E three-pole changeover switch delivers 250 A AC performance across AC21A/AC22A/AC23A duties. With Ui 1000 V and Uimp 8 kV, this GE-series unit supports demanding changeover duties. The GE0250E mounts by screw on plate and provides IP20 frontal protection for safe panel integration.

Rated Ie includes 250 A at AC21A 400/500/690 V, 250 A at AC22A 400/500 V and 200 A at AC22A 690 V, with AC23A 180 A (400 V) and 150 A (500 V). Operational power reaches 100 kW at 400 V AC23A. With 100 kA conditional short-circuit (gG250 fuse), 24 Nm terminals and 10,000 mechanical cycles, it meets IEC/EN 60947-1/-3.
