November 23, 2023 – Mersen has expanded its line of Amp-Trap 15.5kV E-rated bolt-in transformer fuses. By expanding the coverage of the bolt-in mount fuses at the 15.5-kV voltage class to 10E-300E ratings, the company says it can provide “superior protection to a wider range of applications”.

Amp-Trap E-rated fuses are used to protect gear and transformers, and are designed to withstand transformer magnetizing inrush current while delivering overload and short-circuit protection.

The expanded 15.5-kV range includes single, double, and triple barrels, all with a 3-in. diameter (size D). End mounts are designed for bolting directly to equipment bus or terminal pads.
