Reliable Circuit Protection for Power Distribution
Air circuit breakers in the ABB SACE Emax range provide switching and overcurrent protection for high-current low-voltage distribution systems. The electronic trip release monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, feeders and connected equipment against damaging overload and short-circuit conditions.
The PR121/P-LSI release provides long-time protection against sustained overloads, short-time protection for coordinated short-circuit response and instantaneous protection against severe fault currents. Combined with its withdrawable moving-part construction, 1600 A rating and integrated auxiliary status contacts, the 1SDA057597R1 provides dependable protection and practical maintainability for substantial power distribution systems.
Typical Applications
- Industrial low-voltage power distribution systems.
- Withdrawable main switchboards and distribution boards.
- Manufacturing plant electrical distribution.
- Commercial and infrastructure power systems.
- Protection of high-current feeders and busbar systems.
- Three-phase distribution installations requiring electronic LSI protection and withdrawable breaker construction.
