GE0400N - 3P SWITCH DISCONNECTOR W/NH FUSE HOLDER

Why Choose the GE0400N?

The Lovato GE0400N is a three-pole switch disconnector with NH fuse holder designed for dependable AC isolation and protection. With an IEC Ith of 400 A and Ui of 1000 V, it handles demanding distribution duties. The GE0400N offers AC21/AC22 ratings to 400 A and AC23A performance up to 315 A at 690 V, with a conditional short-circuit current of 100 kA.

Engineered for reliability, it delivers 12 kV impulse withstand, IP20 frontal protection and a mechanical life of 10,000 cycles. Rated operational power reaches 220 kW at 400 V and 250 kW at 690 V. The unit mounts securely by screw on plate, operates from -25 to 55 °C up to 3000 m, and meets IEC/EN 60947-1 and 60947-3.
