Overview

The Mersen A155F1D0R0-30E is a 15.5kV E-Rated medium voltage fuse engineered for transformer and distribution line protection in critical electrical infrastructure. This Amp-Trap® fuse features a 30A ferrule termination with a visual indicator for immediate status identification, allowing operators to quickly assess fuse operation without additional testing. Its current-limiting design ensures rapid fault current interruption, melting at as low as 1.7 times its 30A rating while effectively withstanding transformer magnetizing inrush currents to prevent nuisance tripping. The fuse is constructed with a 2-inch diameter barrel (size C) and mounts securely in spring-reinforced clips for reliable contact and stable performance. Rated for a maximum interrupting current of 50kA, it complies with IEEE C37.41-2016 standards for general purpose current-limiting fuses, ensuring consistent operation in demanding applications.
  • 15.5kV maximum voltage rating
