Selectivity (or protection coordination) in low-voltage power distribution systems refers to the ability to precisely isolate a faulty section of the network without disrupting the operation of healthy sections. ABB circuit-breakers, with their advanced technologies, enable full or partial protection coordination in low-voltage networks.
1 – Increased system reliability
2 – Reduced downtime and outages
3 – Faster and more accurate fault diagnosis
4 – Ensured continuity of operation in healthy sections of the network
Smart Circuit-Breakers (e.g., Tmax XT series)
Miniature Circuit-Breakers (S200 and S800 series)

Analysis and overlapping of time-current curves for upstream and downstream circuit-breakers
With over a century of experience in electrical protection, ABB provides reliable solutions compliant with international standards (such as IEC 60947-2 and UL 489). For optimal design of selective protection systems, it is recommended to use ABB’s updated technical catalogs and specialized engineering consultation.
