Advanced High-Fault-Level Power Distribution Protection
Air circuit breakers such as the ABB SACE Emax 2 E2.2H provide switching, isolation and protection for high-current low-voltage distribution circuits. They are commonly installed as incoming, outgoing or bus-coupler breakers in main distribution assemblies where reliable interruption of overload, short-circuit and earth-fault currents is essential for protecting valuable electrical equipment and maintaining continuity of supply.
The Ekip Touch LSIG electronic trip unit combines configurable long-time, selective short-circuit, instantaneous and earth-fault protection with an advanced touch-based interface. Together with the E2.2H platform's high short-circuit breaking performance, these functions make the breaker particularly suitable for complex distribution networks where comprehensive protection, selectivity and high fault-current interruption capability are required.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- Incoming and outgoing feeder protection.
- Bus-coupler and distribution circuit applications.
- Transformer and generator distribution systems.
- Data centres and critical power installations.
- Installations with high prospective short-circuit currents.
