Reliable Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax 3 E2.3B 1600 provide switching and protection for high-current low-voltage electrical distribution systems. Their electronic trip units continuously monitor electrical conditions and initiate protective operation when configured fault conditions occur.
The Ekip Aware LSIG trip unit provides four principal protection functions: long-time protection for overload conditions, short-time protection, instantaneous protection for high-level faults and ground-fault protection. This combination allows the breaker to be configured for demanding power distribution applications.
Typical Applications
- Low-voltage main distribution systems.
- Industrial electrical distribution switchboards.
- Commercial and infrastructure power distribution.
- High-current feeder protection.
- Industrial power control and distribution assemblies.
- Withdrawable switchgear and electrical distribution systems.
