High-Performance Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E4.2H provide switching and protection for high-current low-voltage distribution circuits. The electronic trip unit monitors circuit conditions and initiates interruption when configured protection thresholds are exceeded, helping protect switchgear, conductors and connected equipment against damaging overload and short-circuit currents.

The Ekip Touch LI release combines adjustable long-time overload protection with instantaneous short-circuit protection and an accessible touchscreen interface. Together with the E4.2H frame's high breaking performance and withdrawable architecture, the 1SDA072514R1 provides a robust solution for switchboards where high fault-current capability, reliable electronic protection and maintainability are important.

Typical Applications

• Main incoming protection in high-current low-voltage switchboards.
• Industrial power distribution systems.
• Transformer secondary distribution and protection.
• High-fault-level feeder protection.
• Commercial and infrastructure electrical distribution.
• Power generation and critical power systems.
• Power distribution centres and large electrical installations.
