Overview

The Mersen 61005R is a 600V Class R fuse block designed for reliable circuit protection. This specific model features copper box connectors and is rated for 100 Amperes, suitable for copper wires ranging from #4 to #14 AWG. It is engineered with the same coefficient of expansion as copper wire, ensuring improved heat cycling performance and meeting or exceeding OEM "no aluminum" specifications. The fuse block utilizes GFPC (Glass-Filled Polycarbonate) insulation, providing verified dielectric strength exceeding 2500V for enhanced safety. As an adder block, it can be snapped onto 1-, 2-, or 3-pole blocks to create custom multi-pole configurations. The fuse clips are constructed from high-conductivity tin-plated copper and are spring-reinforced for 100A and above, ensuring a secure connection. This Mersen fuse block is manufactured in the USA and is UL listed (guide IZLT, File E52283) and CSA certified (class 6225, File 32169). It accommodates all Class H, K, and R 250 and 600V power fuses, offering versatile protection for various industrial applications. Recommended mounting screws for 100A blocks are 1/4" (.250" dia.).
