Overview

The Mersen A155F1D0R0-10E Amp-Trap® medium voltage fuse provides reliable overload and short-circuit protection for critical transformer and distribution line assets. Engineered for 15.5kV AC systems, this E-rated fuse features a 10A rating with current-limiting capabilities, melting at currents as low as 1.7 times its rating up to a maximum interrupting rating of 50kA RMS symmetrical. Its design withstands transformer magnetizing inrush currents, ensuring operational continuity. The D0R0 series fuse includes a visual indicator for clear status identification, simplifying maintenance and troubleshooting. With a 3-inch (76.2mm) diameter and 18.87-inch (479mm) length, this ferrule-mounted fuse is designed for mounting in spring-reinforced clips. Compatible with indoor fuse disconnects and supports (e.g., 9F61AGG305/301 for 13.8kV nominal systems), it is suitable for use in enclosures only.
  • 15.5kV AC voltage rating with 10A E-rated ampacity
