GE0400E - 3P CHANGEOVER SWITCH

Why Choose the GE0400E?

Engineered for dependable source transfer, the Lovato GE0400E is a three-pole changeover switch rated 400 A AC. Part of the GE series, this switch delivers Ui 1000 V and Uimp 8 kV performance with IP20 frontal protection. The GE0400E supports AC21A/AC22A/AC23A duties up to 400 A and installs by screw on plate for straightforward panel integration.

Designed for demanding environments, it offers conditional short-circuit current 100 kA with gG400 fuse protection, and a mechanical life of 10,000 cycles. Operating from -25 to 55 °C with IP20 frontal degree and Pollution Degree 3, it meets IEC/EN 60947-1 and 60947-3, with 24 Nm max terminal torque and suitability up to 3000 m altitude.
