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.
