Advanced High-Performance Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect low-voltage electrical distribution systems against overloads and short circuits while providing dependable switching and isolation at high current levels. The Ekip Touch LSI release combines long-time overload protection with short-time selective and instantaneous short-circuit functions, enabling coordinated protection across complex distribution networks.

The E2.2H platform is particularly suited to demanding switchboards where high fault levels, selectivity and maintainability are important. Its high breaking capacity provides robust interruption of severe short-circuit currents, while the withdrawable architecture enables the moving part to be removed from the corresponding fixed section for inspection, maintenance or replacement.

Typical Applications

• Main incoming protection for high-capacity low-voltage switchboards.
• Industrial power-distribution systems.
• Commercial and infrastructure electrical distribution.
• Transformer secondary protection.
• Generator and critical power-distribution installations.
• High-current feeders requiring selective overload and short-circuit protection.
