Advanced Electronic Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E2S800 provide switching and protection for high-current low-voltage distribution circuits. The electronic trip unit monitors current flowing through the breaker and initiates circuit interruption when electrical conditions exceed the configured protection thresholds.
The PR122/P-LI trip unit combines long-time overload protection with instantaneous short-circuit protection. This enables the 1SDA058285R1 to protect cables, switchgear and downstream electrical equipment against sustained overcurrent and severe short-circuit conditions while providing the flexibility associated with electronic protection technology.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main and sub-main electrical switchboards.
- Manufacturing and process industry distribution panels.
- Commercial and infrastructure electrical distribution.
- Protection of high-current feeders.
- Transformer secondary distribution systems.
- Motor control centres and industrial switchgear assemblies.
- Electrical installations requiring electronic overload and instantaneous short-circuit protection.
