Features • Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the needs of higher voltage battery packs. • Higher interrupting rating protects high capacity battery packs needed for vehicle acceleration and range requirements. Transportation During transportation, it shall be rainproof, moisture-proof to avoid severe ground vibration and impact. Temperature Normal condition -5℃～40℃ Allowed condition (Derating) -40℃～100℃ During the rated current test of the fuse, it shall be separately installed in the natural air without ventila- tion, and there shall be no other heating parts or heat dissipation parts within 1m except the connecting wires. When the fuse operates above 20℃ , the rated current needs additional correction. Altitude Allowed condition (Derating) 2000-5000m Parameter correction of altitude change: higher altitude mainly leads to insulation deterioration, heat dissi- pation condition deterioration and air pressure change.
