Comprehensive LSIG Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 provide essential switching and fault protection for high-current low-voltage electrical systems. By detecting abnormal current conditions and interrupting the circuit when configured thresholds are exceeded, the breaker helps protect cables, busbars, switchgear and connected equipment against damaging overload, short-circuit and earth-fault conditions.
The Ekip Dip LSIG release combines long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. Compared with an LSI configuration, the additional G function provides dedicated earth-fault protection, making the 1SDA071583R1 particularly suitable for distribution systems requiring comprehensive fault protection and selective coordination.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical infrastructure.
- Manufacturing and process plant switchgear.
- Transformer-fed distribution systems.
- Systems requiring selective short-circuit and earth-fault protection.
- Infrastructure and utility electrical distribution.
- OEM low-voltage switchgear and busbar assemblies.
