Advanced 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 electrical conditions and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, feeders and connected equipment against damaging overload and fault currents.
The PR123/P-LSIG release provides protection across overload, delayed short-circuit, instantaneous short-circuit and ground-fault conditions. Combined with the withdrawable moving-part construction, four auxiliary contacts and open/closed indication, the 1SDA057525R1 is well suited to sophisticated power distribution systems requiring comprehensive protection, status monitoring and practical maintainability.
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 comprehensive electronic LSIG protection.
