Application Scenarios
GFEVT250‑series fast‑acting high‑speed ev fuse 250VDC 16‑500A is specially developed for new‑energy transportation: EV / HEV battery pack protection, vehicle‑mounted high‑power DC circuits, on‑board charger, energy‑storage DC system. It delivers reliable fast‑acting short‑circuit & over‑current protection for automotive high‑voltage DC platforms.
Installation & Operating Notes
- Bolt‑on mounting; strictly follow specified bolt torque values for each model to avoid bad contact & over‑heating.
- Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating factor for ambient temperature over 40℃.
- For closed‑box / high‑altitude installation (>2000m), implement rated‑current derating according to technical manual.
- Parallel mounting is allowed 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.
- Extra reliability validation test is required for extremely high‑vibration vehicle operating environments.
Packing & Supply
Standard bulk package. Sample testing support, OEM customization, stable mass‑volume supply for new‑energy vehicle & energy‑storage manufacturers. REACH declaration available upon customer request.
