High-Performance Protection for Low-Voltage Distribution

Air circuit breakers such as the ABB Emax 2 E2.2H protect high-current low-voltage distribution systems against damaging electrical faults. The Ekip Dip LSIG electronic release provides coordinated long-time overload, short-time and instantaneous short-circuit protection together with earth-fault protection, helping isolate abnormal conditions while supporting selective protection strategies within the electrical network.

The E2.2H performance level is designed for installations requiring substantial short-circuit capability, with this 800 A configuration providing a 100 kA ultimate breaking capacity at 440 V AC. Its withdrawable architecture also supports maintainability by allowing the moving breaker assembly to be removed from compatible fixed switchgear for inspection, servicing or replacement.
