No. ABB does not produce a manual with that exact name. If you found a file by that name online, it is likely a custom compilation by a third party or a university project document, not an official ABB publication.

This connects the sensors to the electronic unit, ensuring rapid signal transmission to trigger the device unit. 3. Key Sections of the ABB UFES Manual Key Technical Manuals The Comprehensive Guide to the

If you need help locating specific technical data or structural diagrams from a particular revision of the documentation, please let me know:

The is a critical safety system designed to provide active arc fault protection for low- and medium-voltage switchgear systems. Operating up to 40.5 kV and handling short-time currents up to 63 kA , the UFES works by establishing a 3-phase, metallic short-circuit to earth within 1.5 milliseconds of a trip signal. This forces the voltage across an arc flash down to zero, extinguishing the flame in under 4 milliseconds .

The manual provides detailed diagrams for connecting the electronic unit to the device units. This includes:

Always download the Brazilian Portuguese version of the ABB manual if available. ABB Brazil often includes additional notes on NBR standards and local service support numbers (0800-014-9111).
