FRS-R-450 - 450 Amp Fuse

FRS-R-450 - 450 Amp Fuse

Finding the right FRS-R-450 fuse means looking beyond the 450-amp number on the label. For physical compatibility, this model uses blade connections at both ends and measures 13.38 inches long, 3.13 inches high, and 3.13 inches wide. It is also non-indicating, meaning the fuse lacks a built-in status indicator. If you're replacing an existing FRS-R-450, the catalog number and 450A rating give you a useful starting point—but they shouldn't be the only things you compare.
