Reliable LI Protection for High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax E2S provide switching and protection at the heart of low-voltage power distribution systems. The electronic trip unit monitors circuit current and initiates interruption when configured protection thresholds are exceeded, helping prevent overloads and severe short circuits from damaging cables, switchgear and connected equipment.

The PR122/P-LI release fitted to this E2S 1000 combines long-time overload protection with instantaneous short-circuit protection. Together with the E2S frame's 85 kA breaking capacity at 400/415 V AC, four-pole construction and withdrawable format, this configuration provides dependable protection while facilitating isolation and maintenance in important industrial and commercial switchboards.
