UL Class Fuse Reducers

Littelfuse POWR-GARD UL Class fuse reducers allow lower-rated fuses to fit higher-rated fuse blocks, fuse holders, and fused disconnect switches to prevent overfusing. With these fuse reducers, smaller size fuses can fit into existing fuse clips. The LRUH, LRUJ, and LRUR series fuse reducers are intended to be used with UL Class H, J, and R fuses, respectively. These products are designed and manufactured with a variety of features and benefits including easy installation, silver-brazed joints for maximum strength, UL listed, CSA certified, and help to reduce inventory requirements.
