ABB's Ultra-Fast Earthing Switch (UFES) provides active arc flash protection for medium and low-voltage switchgear by creating a controlled 3-phase short-circuit to earth, extinguishing arcs in less than 4 ms. The system uses electronic tripping units and primary switching elements (PSEs) to significantly reduce incident energy and damage, enhancing safety and reducing downtime compared to passive systems.
