Important: DC interrupt capability depends heavily on circuit L/R time‑constant. Confirm actual system L/R 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).

1: 250kA@1500Vdc for L/R ≤5 ms;100kA@1500Vdc for L/R ≤15 ms. DC interrupt performance depends on circuit L/R time‑constant.
2: Can GFHVT1500‑159E be used for container‑scale megawatt BESS main DC bus?
2: Yes. It is designed for utility‑grade large‑capacity energy‑storage DC main‑bus protection. Must perform I²t coordination and L/R time‑constant verification with your BMS & PCS.
3: What are the installation torque requirements for GFHVT1500‑159E?
3: Nut tightening torque:35±4% N·m; M12 set‑screw torque:5‑8 N·m. Improper torque will cause overheating and potential safety risk.
4: What derating shall I use 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 higher‑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.
