Compact footprint

Innovative lateral design drastically reduces switchgear width, cutting construction and operational costs.

Trusted performance

Built on the proven SION platform, ensuring safe and optimized secondary power distribution.

Flexible integration

Left- or right-oriented pole mounting and diverse options ensure perfect fit into any air-insulated panel.

Designed for what it‘s meant to be

Secondary distribution networks do not always strictly require the high availability provided by quickly replaceable withdrawable circuit-breakers. The 3AE6 is specifically designed for these applications, allowing for a simplified fixed-mounted installation.

Lateral design to reduce switchgear width

What truly sets the 3AE6 apart is its innovative lateral operating mechanism. Unlike conventional circuit-breakers, where poles are arranged side-by-side, the 3AE6 positions its poles directly beneath the busbars. This eliminates unnecessary space requirements, enabling a drastic reduction in switchgear width.
