Important: DC interrupt performance subject to actual circuit L/R time‑constant, confirm L/R ratio before project adoption.
Operating & Derating Conditions
Important: Recommended continuous operating current ≤75 % of fuse nominal rating under standard conditions.
Ambient Temperature Derating
Above 40 ℃ ambient temperature requires rated‑current derating according to derating curve. Below ‑5 ℃, pre‑arcing time for low overload will slightly extend.
Altitude Derating
Normal working altitude ≤2000 m. For closed‑enclosure applications at altitude 2000‑4500 m: derate rated current 2‑5 % per 1000 m elevation increase. Air insulation strength drops at high altitude, check clearance per GB/T 16935.1.
Forced Air Cooling Correction
Forced ventilation improves heat‑dissipation and raises allowable continuous operating current, refer to Kv correction curve vs wind‑speed(m/s).
Time‑Current Characteristic Curves
- Curve‑1 covers rating 400‑1200A
- Curve‑2 covers rating 1250‑2000A
- Curve tolerance: ±15 % on current axis. Minimum breaking current＞3 × In.
Frequently Asked Questions
1: What is the interrupt rating and minimum breaking current for GFHVT1500‑D‑105E?
1: 250kA@1500Vdc for L/R ≤5ms; minimum breaking current＞3In. DC interrupt performance is highly dependent on circuit L/R time‑constant.
2: What does D‑type terminal mean?
2: D‑type is four‑M10 bolt‑on bus‑bar connection for high‑current heavy‑duty application, tin‑plated contact surface for anti‑oxidation.
3: Can GFHVT1500‑D‑105E be used for wind‑turbine DC‑link protection?
3: Yes. This high‑current aR fuse is suitable for wind‑power converter DC‑link, large‑scale BESS and heavy‑duty DC‑drive. Need I²t coordination and L/R validation.
4: What derating shall I apply for sealed cabinet working at high altitude?
4: For sealed cabinets operating above 2000 m altitude, derate 2‑5 % per 1000 m elevation. Higher derating ratio applies for larger‑ampacity models.
5: What is suggested maximum continuous operating current?
5: Under standard ambient‑temperature conditions, continuous working current should not exceed 75 % of fuse nominal rated‑current.
