The is a cutting-edge active arc fault protection system designed to extinguish internal arcs in less than 4 milliseconds . By rapidly creating a 3-phase metallic short-circuit to earth, the UFES system redirects uncontrolled arc energy into a controlled path, protecting personnel and minimizing equipment damage. System Architecture and Components
Once you have downloaded the correct ABB manual for your UFES equipment, here is a quick guide to its structure. Most ABB manuals follow this pattern: abb+ufes+manual
