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-sized 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.
