Description:
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 250V fuse
into a 600V block or a 600V fuse into a 250V
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.
