Advanced Generator and LSIG 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 electronic trip unit monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect switchgear, conductors, generators and connected equipment against overload, short-circuit and ground-fault currents.

The Ekip G Touch LSIG release combines comprehensive LSIG protection with generator-oriented functionality and touchscreen operation. Together with the E6.2H frame's 100 kA short-circuit performance and withdrawable architecture, the 1SDA072587R1 provides a robust solution for installations where high-current capability, selective electronic protection and maintainability are essential.

Typical Applications

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