Advanced LSIG Protection for High-Fault-Level Distribution

Air circuit breakers such as the ABB Emax 2 E2.2H protect high-current low-voltage distribution systems against overload, short-circuit and earth-fault conditions while providing controlled switching and isolation. The E2.2H performance level is particularly suited to installations with high prospective fault currents, delivering substantial interruption and short-time withstand capability for demanding electrical networks.

The Ekip Hi-Touch LSIG electronic trip unit combines long-time, selective short-time and instantaneous overcurrent protection with earth-fault protection. This comprehensive protection package supports selective system coordination while helping protect conductors, switchgear and connected equipment against a wide range of electrical fault conditions.

Typical Applications

• Main low-voltage switchboards and power distribution boards.
• High-fault-level industrial electrical systems.
• Manufacturing and process facilities.
• Data centres and critical power infrastructure.
• Commercial and infrastructure electrical distribution.
• Transformer and installation protection.
• Main incomer and high-current feeder protection.
• Systems requiring integrated earth-fault protection.
