Advanced Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect low-voltage distribution systems against abnormal current conditions while providing switching and isolation at high current levels. The Ekip Touch LSI release monitors the circuit electronically and provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection, allowing the breaker to be coordinated with other protective devices in the distribution network.

The withdrawable E2.2 platform is particularly suited to critical switchboards where maintainability and continuity of service are important. Its high short-time withstand capability supports selective coordination, while the modular Emax 2 architecture enables the circuit breaker to form part of sophisticated industrial power-distribution and energy-management systems.

Typical Applications

• Main incoming protection for low-voltage switchboards.
• Industrial power-distribution systems.
• Commercial and infrastructure electrical distribution.
• Transformer secondary and distribution protection.
• Generator and installation protection systems.
• High-current feeders requiring selective circuit protection.
