GE0400ET4 - 4P CHANGEOVER SWITCH

Why Choose the GE0400ET4?

The Lovato GE0400ET4 four-pole changeover switch delivers dependable source transfer for AC circuits with a 400 A Ith rating. As a robust changeover switch, SKU GE0400ET4 mounts screw-on plate and offers a frontal IP20 degree for operator protection. Ui is 1000 V with 8 kV Uimp, supporting secure performance in industrial control and distribution.

Built to IEC/EN 60947-1 and 60947-3, the GE series defines clear duties: AC21A/AC22A up to 400 A across 400/500/690 V, and AC23A up to 250 A at 400 V. With 100 kA conditional short-circuit current (gG400 fuse), 10,000 mechanical cycles and -25 to 55 °C operation, it ensures reliable switching and straightforward integration.

Key Benefits

• 400 A Ith handles high-capacity AC changeover with confidence.
• Four-pole configuration supports simultaneous switching of multiple conductors.
