ABB has extended its capabilities by merging UFES with digital relays. The solution combines the UFES hardware with protection relays. This creates an all-in-one solution that merges arc flash mitigation with advanced grid automation and communication protocols (IEC 61850).

Discard the deployed UHEV cartridges. Install brand-new, factory-certified ABB UHEV elements.

There are several approved configurations for mounting the UFES Service Box, depending on the physical layout of the switchgear:

The intelligence of the system resides in the electronic unit. It evaluates sensor inputs and triggers the PSE. abb+ufes+manual

To facilitate easy integration, ABB offers a type-tested UFES Service Box. This proprietary enclosure contains the UFES components and can be mounted directly onto switchgear systems, connected by copper bars to the main busbar.

Continuously monitors the system for signs of a fault.

directly to the switchgear frame, accounting for short‑circuit forces. The box is then connected to the main busbar via copper bars that must be sized and torqued correctly. ABB has extended its capabilities by merging UFES

He found the diagram. It was dense, filled with hexadecimal codes and logic gate schematics that looked like a foreign language to the uninitiated. But to Elias, it was poetry.

If the unit fails to trip during a secondary injection test or light simulation:

Internal error detected (e.g., sensor loop broken, auxiliary battery low, or internal capacitor failure). The system requires immediate technician evaluation. Discard the deployed UHEV cartridges

"I found something," Mariana said, her voice dropping. She turned her laptop screen toward him. It wasn’t a website. It was a directory listing on an old UFES department server—a dusty corner of the university's intranet that hadn't been updated since 2005.

– each phase’s PSE is bolted to the busbar on the line side and to a grounded terminal on the load side. The manual specifies the required short‑circuit strength of the connections.
