Advanced LSI Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E6.2H provide switching and protection for high-current low-voltage distribution circuits. The Ekip Hi-Touch electronic trip unit monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect switchgear, conductors and connected equipment against overload and short-circuit currents.

The Ekip Hi-Touch LSI release combines long-time overload protection with short-time delayed and instantaneous short-circuit protection alongside advanced electronic functionality. Together with the E6.2H frame's 100 kA short-circuit performance and withdrawable architecture, the 1SDA072588R1 provides a robust solution where high-current capability, selective protection and maintainability are required.

Typical Applications

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