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. Electronic trip units continuously monitor circuit current and initiate breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars, switchgear and connected equipment against damaging electrical faults.
The PR121/P-LI release provides essential long-time and instantaneous protection functions, while the withdrawable Emax construction allows the circuit breaker moving part to be isolated and removed from compatible switchgear for servicing. This combination makes the E1N1000 suitable for installations where dependable protection, maintainability and continuity of electrical distribution are important.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchgear.
- Power distribution panels and switchgear assemblies.
- Infrastructure and utility installations.
- Protection of feeders, busbars and distribution circuits.
