GE0400 - 3P SWITCH DISCONNECTOR

Why Choose the GE0400?

Designed for dependable isolation in industrial AC systems, the Lovato GE0400 Switch Disconnector delivers three-pole switching at 400 A. This compact, plate-mounted device (SKU GE0400) supports duties across AC21A to AC23A categories, providing safe isolation and robust performance. Built by Lovato and compliant with IEC/EN 60947 standards, it integrates easily into control panels and switchboards where reliable disconnection and maintenance safety are essential.

With Ui 1000 V and Uimp 8 kV, the GE0400 withstands demanding conditions, offering IP20 frontal protection. Operational currents include AC23A: 400 A (400 V), 315 A (500 V), and 160 A (690 V). It delivers a 100 kA conditional short-circuit rating with gG400 fuse and a 20,000-cycle mechanical life. Operating range is -25 to 55 °C, with installation up to 3000 m altitude.
