High-Performance Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E6V protect high-current low-voltage distribution systems against overloads and short circuits. When configured protection thresholds are exceeded, the breaker interrupts the affected circuit, helping safeguard switchgear, cables, transformers, generators and connected electrical equipment against potentially damaging fault conditions.
The PR122/P-LI electronic release provides long-time and instantaneous protection functions. Long-time protection responds to sustained overload conditions, while instantaneous protection provides rapid circuit interruption during severe short-circuit faults, helping protect valuable electrical distribution equipment and maintain system reliability.
Typical Applications
- Main low-voltage distribution switchboards.
- High-current industrial power distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer secondary distribution.
- Generator and installation protection systems.
- High-fault-level switchgear assemblies.
- Power distribution systems requiring high-capacity overload and instantaneous short-circuit protection.
