Part Number List & Electrical Parameters

Application Scenarios

GFEVF150‑Series aR Semiconductor DC Power Fuse 125‑150VDC 70‑1000A is built for low‑voltage DC new‑energy applications: energy‑storage battery‑pack, DC drives, power converters, rectifier equipment and DC relay backup protection. The aR‑class high‑speed characteristic provides reliable short‑circuit protection for power semiconductor devices under heavy fault‑current conditions.

Installation & Operating Notes

• Bolt‑on mounting type; apply correct bolt torque value to avoid poor contact and over‑heating risk.
• Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating factor for ambient temperature over 40℃.
• For closed‑box installation or altitude >2000 m: closed‑box environment requires 2%‑5% current derating per 1000 m altitude rise; open‑air installation can normally ignore altitude influence.
• Parallel mounting permitted only within dimensional and specification guidelines to achieve 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 working environments.
• Select matched copper conductor cross‑section for terminals to control temperature‑rise performance.

Packing & Supply

Standard bulk package. Sample testing support, OEM customization, stable mass‑volume supply for energy‑storage and power‑converter manufacturers. REACH declaration available upon customer request.
