Blade Fuses
MAXI Blade Fuses Rated 58V
The MAXI® style fuse for use in 42V Systems. Same Time-Current characteristic as the 32V
MAXI fuse using “Diffusion Pill Technology” to provide predictable time delay characteristics
and low heat dissipation. Fits into standard MAXI® fuse sockets. Has a rejection feature to
prevent fuses with lower voltage rating from being wrongfully inserted into the circuit. Current
rating 20A - 80A @58 VDC max.

Temperature Rerating Curve
Dimensions in mm
*Component Level Temperature = the maximum ambient
temperature that a single fuse will survive. This does not
factor-in the heat from a populated fuse box, but does include
the heat from the current load with the proper rerating.
**System Level Temperature represents the ambient
temperature of the fuse box at a location within the vehicle.
The temperature within a populated fuse box (in a given
location) will be higher. The limiting factor is the plating.
Sn-plating’s temperature limit is ≈130°C, and Ag-plating allows
up to 150°C at the terminal interface.
