Advanced Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB E2H-A 800 provide switching and protection for high-current low-voltage distribution circuits. They are commonly applied to incoming, feeder and distribution circuits where dependable interruption of overload and short-circuit faults is essential for maintaining electrical system safety, availability and continuity of service.
The PR122/P electronic trip unit monitors circuit current and initiates breaker operation when configured protection thresholds are exceeded. Its LSI functionality provides short-time protection between the long-time and instantaneous functions, supporting selective coordination and helping isolate faults while minimising unnecessary interruption to unaffected sections of the electrical network.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Incoming and feeder circuit protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Selective and coordinated low-voltage protection systems.
