With more focus on the Power In and Medium Voltage equipment, there is massive arc flash risk at that level.
Mersen has created and designed a fuse system to mitigate the Arc-Flash hazard on the low-voltage side of a medium voltage transformer. It's the industry’s first fuse to provide normal short-circuit and overload protection while having the capability to open on command, this fuse is a cost effective arc flash solution with minimal installation downtime.
There is no messing around on the the Medium Voltage side. That stuff really could be life threatening.
