Installation & Operating Notes
- Stud‑mount installation; tighten stud nuts with proper torque value, prevent bad contact and excessive temperature‑rise.
- Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating factor when ambient temperature exceeds +40℃, follow temperature‑re‑rating curve.
- Standard application altitude ≤2000m; above‑2000‑meter deployment, please consult manufacturer for current‑derating advice.
- Designed for vehicle‑grade harsh vibration environment (JASO D622‑2006 verified); still need to avoid severe continuous mechanical impact.
- Do NOT replace fuse under live DC‑load without certified load‑break protection device.
- Replace fuse immediately if shell crack, deformation or mechanical damage appears.
- Transport & storage: avoid water infiltration and mechanical collision damage.
- For operating conditions beyond datasheet specification range, please contact factory for technical support.
Packing & Storage Requirements
Standard bulk package. Avoid water seepage and mechanical damage during transportation and storage. Normal operating ambient:‑5℃~+40℃, relative humidity ≤50%@40℃; higher humidity allowed under low‑temperature condition (90%RH@20℃). Sample testing support, OEM customization for automotive new‑energy customers. REACH declaration available upon customer request.
