Part Number List & Electrical Parameters

Сценарии применения

GFBMG5‑Series Square‑Body Fast‑Acting aR ESS DC Fuse 2000VDC 1400‑3000A is specially developed for heavy‑duty high‑voltage DC new‑energy projects. Mainly applied for large‑scale industrial energy‑storage systems, high‑power DC converter cabinets. aR‑class high‑speed performance provides reliable short‑circuit protection for power semiconductors and high‑power DC equipment under severe fault‑current conditions.

Installation & Operating Notes

• #5 square‑body with five M12 mounting holes; apply specified bolt torque to avoid poor contact and over‑heating risk; terminal tin‑plated 3‑5μm.
• Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating‑factor Kt for ambient temperature over 40℃.
• Altitude ≤2000m no‑derating; for closed‑box installation within 2000‑4500m altitude: derate 2%‑5% rated‑current per 1000m elevation increase. Open‑air installation can normally ignore altitude impact.
• Insulation clearance needs to be re‑checked at high altitude, refer to GB/T16935.1 standard.
• Parallel mounting permitted 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 on fuse body.
• Additional reliability validation test shall be conducted for extremely high‑vibration industrial working environments.
• Select matched copper conductor cross‑section for terminals to control temperature‑rise performance.

Packing & Storage Requirements

Standard original‑box bulk package. Store in clean, dust‑free warehouse environment. Storage temperature:‑40℃~+85℃; humidity limit: RH≤70%@40℃, RH≤80%@30℃, RH≤90%@20℃.
