Zillion SFS
Smart fuse switch | lower solution

The SFS – Bottom-Mounted Smart Fuse Switch is an integrated solution that combines protection, sensing and advanced electrical monitoring directly at the feeder level within the low-voltage switchboard. This enables accurate electrical measurement without the need for additional external devices, simplifying the system architecture from the outset.

The solution natively integrates the SAL – Advanced Line Supervisor together with the TSA – Advanced Supervision Board, incorporating current transformers directly into the fuse switch base. As a result, the SFS transforms conventional protection into an intelligent asset capable of generating reliable and comparable electrical data.

In addition, its bottom-mounted design supports a compact and organised switchboard layout. It also allows the safe replacement of electronic boards while energised, without interrupting the power supply, improving operational continuity.

As part of the Zillion ecosystem, the SFS provides a solid foundation for advanced network monitoring, diagnostics and operation. The data collected can therefore be used consistently alongside the rest of the ecosystem’s solutions.
