A range of Bussmann™ series fuse reducers for Class H/K, J and R ferrule and blade fuses. Fuse reducers install on fuse ferrules or blades to permit the application of smaller size fuses than those for which the fuse blocks or holders are designed. The following conditions and limitations apply to the fuse reducers listed in this data sheet: • There are no reducers to fit a 250 V fuse into a 600 V block or a 600 V fuse into a 250 V block. • Fuse reducers for fuse blocks or holders intended for current-limiting fuses will not accept non-current limiting fuses. • There are no reducers for Class T fuses. • By design, Class L fuses do not require reducers. Further limitations are detailed in the catalog number tables.
