Coordination

Selected Optimized Coordination – SOC Online tool
ABB offers a quick and easy way to find the best coordination between circuit- breakers with
SOC Online tool.
This tool is not limited to molded-case circuit-breakers, but it includes constantly updated coordina-
tion tables for a wide range of ABB protection devices.
Tables can be examined directly online but is also possible to download a PDF version to have a ready to
use project documentation.

Step 1
Set your country/language preferences or read the help pages

Choose the coordination type

Step 2

Table with coordination results (expressed in kA):
• numeric value: represents the max value of
short circuit current for which the upstream de-
vice is selective (or it guarantees back-up) to-
wards the downstream device;
• empty cells: means that for the relative rated
currents the selectivity/back-up cannot be
* Filters can be set without a fixed sequence. If a filter has been
modified, others will be kept (if allowed by the conditions). achieved;
**This is only valid for selectivity. • T**: means that the upstream device assures
selectivity up to the Icu value of the down-
stream device (Total Selectivity)
