Comprehensive LSIG Protection for High-Current Power Distribution
Air circuit breakers such as the ABB Emax 2 E4.2S protect high-current low-voltage distribution systems against overload, short-circuit and earth-fault conditions while providing controlled switching and isolation. With a 4000 A current rating and substantial fault-interruption capability, this E4.2S configuration is well suited to main distribution points, transformer secondaries and other high-current sections of electrical installations.
The Ekip Dip LSIG electronic trip unit combines long-time overload, selective short-time and instantaneous short-circuit protection with integrated earth-fault protection. Adjustable protection thresholds support coordination between upstream and downstream protective devices, while the Ekip Dip interface provides a straightforward method of configuring essential protection settings directly at the circuit breaker.
Typical Applications
- Main low-voltage switchboards and power distribution boards.
- High-current industrial electrical distribution systems.
- Manufacturing and process facilities.
- Data centres and critical power infrastructure.
- Large commercial and infrastructure installations.
- Transformer secondary and main incomer protection.
