Selective Protection for Low-Voltage Distribution Systems

Air circuit breakers such as the ABB Emax 2 E1.2C provide switching and protection for low-voltage electrical distribution systems. By detecting overload and short-circuit conditions and interrupting fault current, the breaker helps protect switchboards, cables, busbars and connected electrical equipment while supporting dependable operation of the wider electrical installation.

The Ekip Dip LSI release combines adjustable long-time overload, short-time short-circuit and instantaneous short-circuit protection. The short-time function supports selective coordination between protective devices, helping isolate faults closer to their source while maintaining continuity of supply to unaffected sections of the electrical network.

Typical Applications

• Low-voltage main and sub-distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Three-phase four-wire distribution networks.
• Transformer secondary-side protection.
