Advanced LSIG Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E3N3200 provide switching and protection for high-current low-voltage distribution circuits. The electronic overcurrent release monitors electrical conditions and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, switchgear and connected electrical equipment.
The PR122/P-LSIG release combines long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection within an electronic trip unit. Together with the E3N frame's 3200 A current capability, 65 kA short-circuit performance and three-pole fixed construction, this configuration provides comprehensive protection for main distribution and high-current feeder circuits.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plant switchgear.
- Commercial building electrical distribution.
- Infrastructure and utility installations.
- Main incomer and high-current feeder protection.
- Three-phase distribution systems requiring earth-fault protection.
- High-current fixed circuit breaker switchboard assemblies.
