GE0250N - 3P SWITCH DISCONNECTOR W/NH FUSE HOLDER

Why Choose the GE0250N?

Built for dependable isolation and protection, the Lovato GE0250N is a three-pole switch disconnector with NH fuse holder rated at 250 A. Designed for AC systems, it combines compact plate-mount convenience with finger-safe IP20 frontal protection. With a 1000 V rated insulation (Ui) and 12 kV impulse withstand (Uimp), this GE series unit delivers robust performance for control panels and distribution assemblies.

The GE0250N supports demanding duty categories with Ie ratings: AC21A up to 250 A across 400–690 V, AC22A up to 250 A (200 A at 500 V), and AC23A up to 250 A at 400/500 V (200 A at 690 V). Rated operational power reaches 132 kW at 400 V and 160 kW at 690 V. It offers 100 kA conditional short-circuit capability, 10,000 mechanical cycles, and screw-on plate installation to IEC/EN 60947-1 and 60947-3.
