Installation & Operating Notes
- Flush bolt‑on mounting; strictly follow specified bolt torque value for each current rating to prevent poor contact & over‑heating.
- Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating factor for ambient temperature over 40℃.
- For closed‑box / high‑altitude installation (>2000m), perform rated‑current derating according to technical datasheet.
- Parallel mounting allowed only within dimensional and specification guidelines for higher ampacity.
- Do NOT replace fuse under live DC load unless equipped with certified load‑break switchgear.
- Replace fuse immediately if mechanical damage, crack or deformation occurs.
- Additional reliability validation is required for extremely high‑vibration vehicle working environments.
Packing & Supply
