Bussmann NO.2641-R Fuse Block Reducer, 400A to 100A

This Bussmann fuse block reducer is engineered to adapt a 400A fuse clip so it can accept a 100A fuse, giving electricians and maintenance teams a practical way to modify circuit protection without swapping out an entire fuse block or panelboard. Identified by the "R" designation in the Bussmann catalog system, this reducer is built to mate with compatible Bussmann fuse holders and distribution equipment sized for 400A fuses. It offers a straightforward path to step down amperage capacity from 400A to 100A while keeping the existing fuse block footprint intact, helping simplify retrofits, upgrades, and load changes on industrial and commercial electrical systems.

Key Features

  • Amperage Reduction: Converts a 400A fuse block or clip to accept a 100A fuse, matching the product's R-style catalog designation.
  • Panel Compatibility: Designed to fit Bussmann fuse blocks and holders originally sized for 400A fuses, allowing installation of a lower-amperage 100A fuse without replacing the block.
  • R Reducer Design: The "R" designation identifies this component as an R-style reducer within the Bussmann fuse accessory catalog.
  • Space-Saving Solution: Eliminates the need to remove and replace an entire fuse block or panelboard section when a lower-ampere fuse rating is required.
  • Application Flexibility: Supports maintenance work, equipment upgrades, and circuit modifications where amperage requirements have changed from the original 400A design.
