Littelfuse LRUR Series Fuse Reducer, Fuse Clip Adapter
The Littelfuse LRUR Series Fuse Reducer, also cross-referenced in Littelfuse catalogs as the LRU2 Series, is available across the LRU216R, LRU226R, and LRU2664R models within Littelfuse's Fuse Reducers product family. These fuse reducers adapt fuse mounting configurations, allowing a smaller-frame fuse to be installed securely into a fuse clip or fuse block that was originally sized for a larger fuse class, without requiring a full fuse block replacement. Electrical professionals and maintenance teams use the LRUR Series as a clear reference point when specifying replacement or upgrade components for power fuse distribution equipment, and keeping the correct reducer on hand helps streamline maintenance on panels that mix multiple fuse sizes within the same fuse block footprint.
