Comprehensive LSIG Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current electrical distribution systems against potentially damaging fault conditions. By automatically interrupting the circuit when configured protection thresholds are exceeded, the breaker helps safeguard cables, busbars, switchgear and connected equipment while supporting reliable operation of the wider electrical installation.

The Ekip Dip LSIG trip unit combines long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. This comprehensive protection package makes the E1.2N particularly suitable for main and distribution switchboards where effective selectivity, high fault-current interruption capability and protection against earth faults are required.

Typical Applications

• Main low-voltage electrical distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical infrastructure.
• Manufacturing and process plant switchgear.
• Transformer and generator distribution systems.
• Electrical installations requiring earth-fault protection.
• Infrastructure and utility power distribution.
