Installation & Operating Notes

• Square‑body flush‑end contact with 2‑M10 mounting holes; max hole depth 11.5mm, min thread length 9.5mm. Apply specified bolt torque to avoid poor contact and over‑heating risk.
• Recommended continuous operating current ≤75% of fuse rated‑current. Apply temperature‑derating‑factor Kt for ambient temperature above +40℃.
• Altitude ≤2000m no‑derating; closed‑box installation between 2000‑4500m: derate 2%‑5% rated‑current per 1000m elevation increase. Re‑check insulation clearance according to GB/T16935.1 for high‑altitude deployment.
• Supports vertical, horizontal and inclined mounting; minimize negative gravity‑vibration impact on electrical contact performance.
• Forced‑air cooling improves heat dissipation and increases allowable operating current, refer to Kv correction coefficient.
• Do NOT replace fuse under live DC load unless equipped with certified load‑break switchgear, strictly follow 1500VDC high‑voltage safety operation procedure.
• Replace fuse immediately if shell crack, deformation or mechanical damage appears.
• Additional reliability validation test required for extremely high‑vibration industrial working conditions.
• Select matched copper conductor cross‑section for terminals to control temperature‑rise performance.
• Ordering reminder: part numbers with remark “Pending”, please confirm factory status before order placement.
