The ABB UFES is an active protection device rather than a passive safety feature. It actively creates a safe condition in just a few milliseconds by short-circuiting the fault to ground. From the simple "Service Box" installation to complex digital retrofits with Relion relays, the UFES adapts to a wide range of low- and medium-voltage environments.
Imagine a scenario where ABB collaborates with UFES (as a representative of educational and research institutions) on projects that aim to fuse manual craftsmanship with technological innovation. Such collaborations could involve research in advanced robotics, development of new materials, or creation of more efficient industrial processes. Students and researchers at UFES could engage in hands-on projects sponsored by ABB, applying theoretical knowledge to real-world problems and developing solutions that blend manual dexterity with technological acumen.
ABB also offers that cover these maintenance routines. The official UFES training (e.g., the 2‑day course at ABB’s Training Center in Ratingen, Germany) is structured as 40% theory and 60% hands‑on practice on real equipment, with a maximum group size of 5 participants. abb+ufes+manual
The ABB Ultra-Fast Earthing Switch (UFES) is a cutting-edge active arc fault protection system designed to protect personnel and electrical equipment from the destructive effects of internal arc faults. By rapidly grounding the system, the UFES extinguishes an arc fault in less than 4 milliseconds, significantly reducing the incident energy released.
The technical performance of the UFES system is defined by key speed and power ratings. The ABB UFES is an active protection device
For specific engineering needs, the UFES is also available as standalone "loose apparatus" (the electronic unit and three PSEs). This is for custom panel builders or EPCs who need to integrate the solution into non-standard enclosures.
This instruction is targeted toward operation, inspection, and maintenance personnel. Imagine a scenario where ABB collaborates with UFES
