I²T fuse
For
50 amp model: 63A or less, for example: Bussman FE63. For 75 or 100 amp model:
100A or less, for example: Bussman FE100. For installations >75 amps, or in
warm installations, an external I²T fuse and fuse block can be used and a
Power-io bus bar can be inserted in place of the internal fuse. See our
fuse
bulletin.pdf for additional fuse information.
