Reliable Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE New Emax E3H-A protect high-current electrical distribution systems against damaging overload and short-circuit conditions. By monitoring circuit current through an electronic protection release, the breaker can interrupt the electrical supply when operating conditions exceed configured protection thresholds, helping safeguard cables, switchgear and connected equipment.

The PR122/P-LSI electronic release provides long-time, short-time and instantaneous protection functions, allowing coordinated protection across complex electrical distribution networks. Combined with the withdrawable Emax construction, the 1SDA057609R1 is particularly suitable for installations requiring dependable high-current protection together with convenient breaker isolation and maintenance.
