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. Specifications Voltage Rating: 58 VDC Interrupting Ratings: 1000A @ 58 VDC *Component Level Temperature Range: -40˚C to +125˚C **System Level Temperature Range: -40˚C to +105˚C MAXI Blade Fuses 105°C is a typical system level temperature requirement. Terminals: Ag plated zinc alloy Housing Material:PA66 Complies with: SAE J 1888, SAE 2576 ISO 8820-3:2002(E) Ordering Information Part Number Time-Current Characteristic Curves Time-Current Characteristics Package Size % of Rating Opening Time Min / Max (s) 1200 100 360,000 s / – 135 60 s / 1,800 s 0999xxx.ZXN Ratings Part Number Current Rating (A) 0999020._ 0999025._ 2 s / 60 s 350 0.20 s / 7 s 600 0.040 s / 1 s Typ.

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.
