Advanced LSIG Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 E2.2S 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 and connected equipment against damaging overload, short-circuit and ground-fault currents.
The Ekip G Touch LSIG release combines long-time overload, short-time and instantaneous short-circuit protection with integrated ground-fault protection. Together with the E2.2S frame's high breaking performance and withdrawable architecture, this provides a flexible protection solution for demanding switchboards, power distribution systems and generator-related applications.
Typical Applications
- Main incoming protection in low-voltage switchboards.
- Industrial power distribution systems.
- Generator protection and power distribution applications.
- High-current feeder protection.
- Commercial and infrastructure electrical distribution.
- Transformer secondary distribution systems.
- Power distribution centres and critical electrical installations.
