Advanced LSI Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E4H protect major low-voltage distribution circuits while providing dependable switching and isolation. Electronic protection monitors electrical conditions and initiates tripping when configured protection thresholds are exceeded, helping safeguard cables, busbars, switchgear and downstream equipment from potentially damaging overload and short-circuit conditions.

The PR122/P-LSI R3200 release fitted to the 1SDA056836R1 provides comprehensive long-time, short-time and instantaneous overcurrent protection. Combined with its 3200 A current rating, three-pole construction, 100 kA breaking capacity at 415 V AC and withdrawable execution, this E4H moving part is well suited to major distribution boards where high fault levels, advanced electronic protection and convenient circuit-breaker maintenance are required.
