. It functions by initiating a 3-phase short-circuit to earth, which rapidly drops the arc voltage and extinguishes the fault before significant pressure or thermal damage occurs. System Components Protecting People and Power: A Guide to ABB’s

1. ABB Equipment deployed at UFES (the university): A technician needs the operation manual for an ABB drive, UPS, or circuit breaker installed at the Universidade Federal do Espírito Santo in Brazil.
2. A specific ABB product series: Some users mistakenly believe "UFES" is a product line. In reality, ABB does not have a standard "UFES" product series. The closest matches are the ABB UPS Megadial or PowerValue series.
3. Academic collaboration: Engineering students at UFES searching for manuals related to ABB laboratory equipment.

Tripping: Once an arc is identified, the UFES electronics trigger the PSEs in less than 1 ms. ABB Equipment deployed at UFES (the university): A

4. Installation & Wiring

4.1. Mounting

• The UFE relay should be mounted on a DIN rail or screwed onto a panel in the low-voltage compartment of the switchgear.
• Ensure the environment meets the IP rating requirements (usually IP54 for the front panel).
