Selective Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect low-voltage electrical distribution systems against damaging overloads and short circuits while providing dependable switching at high current levels. The Ekip Dip LSI release combines long-time overload protection with short-time delayed and instantaneous short-circuit functions, allowing protection settings to be coordinated with downstream devices.

The E2.2S platform is particularly suited to demanding switchboards where breaking capacity, selectivity and maintainability are important. Its 66 kA short-time withstand capability supports selective protection strategies, while the withdrawable construction enables the moving part to be removed from its corresponding fixed section for servicing or replacement.

Typical Applications

• Main incoming protection for 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.
