Why Choose the ABB S751DR-E80 Selective Circuit Breaker?
The ABB S751DR-E80 is a high-performance 1-pole selective circuit breaker designed to provide dependable overload and short-circuit protection in electrical distribution systems. Part of the ABB S750 selective circuit breaker family, it combines a rated current of 80 A, Type E characteristic and a high 25 kA breaking capacity.
The selective operating design is intended to support coordinated protection within distribution networks, helping downstream protective devices clear faults while maintaining continuity in unaffected sections where suitable selectivity conditions are achieved. This makes the S751DR-E80 particularly useful in installations where dependable protection and distribution-system availability are important.
With its 80 A rated current, single-pole configuration and 25 kA short-circuit breaking capability, the S751DR-E80 provides robust protection for demanding distribution applications. Its modular format supports integration into suitable electrical distribution boards and switchgear assemblies.

Selective Protection for Reliable Electrical Distribution
Selective circuit protection is used to coordinate protective devices so that a fault can be disconnected as close as practical to its source. The ABB S751DR-E80 is designed for this type of distribution architecture, helping reduce unnecessary interruption to unaffected circuits when appropriate upstream and downstream protective devices are correctly coordinated.
Combining an 80 A rating with a high 25 kA breaking capacity, the S751DR-E80 is suitable for distribution environments where substantial prospective fault currents may occur. Its Type E characteristic and selective design make it a specialised protection solution for appropriately engineered commercial and industrial electrical systems.
Typical Applications
- Selective electrical distribution systems.
- Commercial and industrial distribution boards.
- Main and sub-distribution assemblies.
- Higher-current distribution circuits.
- Installations requiring coordinated upstream and downstream circuit protection.
- Distribution applications requiring high short-circuit breaking capacity.
