Reliable Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E1N are designed to switch and protect high-current low-voltage distribution circuits. The electronic trip unit continuously monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded, helping protect electrical infrastructure against overloads and short circuits.
The PR121/P-LSI release provides long-time, short-time and instantaneous protection functions, allowing the breaker to respond appropriately to different fault conditions. Combined with the fixed E1N construction and high short-circuit capability, this makes the E1N1000 well suited to main and feeder protection in industrial and commercial switchboards.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchgear.
- Transformer and feeder protection.
- Power distribution panels and switchgear assemblies.
- Infrastructure and utility installations.
- Protection of busbars and high-current distribution circuits.
