Reliable Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E3H are designed to switch and protect high-current low-voltage distribution circuits. The PR122/P electronic trip unit monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded, helping safeguard cables, busbars, transformers, switchgear and connected equipment against damaging overload and short-circuit conditions.
The PR122/P-LSI release combines adjustable long-time, short-time and instantaneous protection with the substantial short-circuit performance of the E3H frame. Combined with its withdrawable construction, the E3H1000 is particularly well suited to main and feeder protection where high fault-current capability, selective coordination and service-friendly breaker removal are important.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchgear.
- Transformer and feeder protection.
- High-fault-level distribution systems.
- Power distribution panels and switchgear assemblies.
- Infrastructure and utility installations.
- Protection of busbars and high-current distribution circuits.
