GE0630N - 3P SWITCH DISCONNECTOR W/NH FUSE HOLDER

Why Choose the GE0630N?

Engineered for dependable three-phase isolation, the Lovato GE0630N switch disconnector with NH fuse holder delivers 630 A Ith for heavy-duty AC applications. This three-pole, screw-on-plate device integrates disconnection and fuse protection in one compact unit, streamlining panel layouts. Built to the GE series design, it supports rigorous industrial requirements where safe, clear isolation and coordinated protection are essential.

Rated Ui 1000 V with 12 kV impulse withstand, it achieves AC21A/AC22A currents of 630 A up to 690 V, and AC23A 400 A at 690 V. Performance includes 100 kA conditional short-circuit capability, IP20 front protection and a mechanical life of 5,000 cycles. Designed for -25 to 55 °C operation and screw-on-plate installation, it features NH fuse acceptance and 45 Nm max terminal torque, meeting IEC/EN 60947-1 and 60947-3.
