Comprehensive Circuit and Earth-Fault Protection
Air circuit breakers such as the ABB SACE Emax 2 E1.2B protect low-voltage electrical distribution systems against potentially damaging overload, short-circuit and earth-fault conditions while providing dependable switching and isolation. With a 1600 A rated current and 42 kA breaking capacity up to 690 V AC, this E1.2B configuration provides robust protection for substantial switchboards, feeders and connected electrical equipment.
The Ekip Dip LSIG electronic trip unit combines four principal protection functions in one configurable release. Long-time protection addresses sustained overloads, short-time protection supports selective coordination, instantaneous protection responds rapidly to severe short circuits, and earth-fault protection provides an additional layer of protection against ground faults. DIP-switch adjustment and the Emax 2 withdrawable architecture provide a practical combination of configurable protection and maintainability.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
