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 Curve
Covers rating 100‑400A. Curve tolerance: ±15 % on current axis. Minimum breaking current =5 × In.
Frequently Asked Questions
1: What is the minimum breaking current for GFHVT1500‑A‑59E series?
1: Minimum breaking current equals 5 times nominal rated current(5In).
2: What does flush‑end‑contact terminal mean?
2: Flush‑end contact (Type‑A) is flat end‑face mounting with two M10 holes, designed for compact rack installation to save cabinet internal space.
3: Can GFHVT1500‑A‑59E be used for lithium‑ion battery‑module protection?
3: Yes. It is aR‑class fast‑acting flush‑end fuse for battery‑module and compact‑BESS DC‑circuit protection. Please verify I²t coordination with your BMS.
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.
