응용 시나리오
GFEVT500‑18R series fast‑acting ev dc fuse 500VDC 10‑100A applies to new‑energy transportation and energy‑storage markets: EV / HEV battery‑pack protection, DC relay backup protection, maintenance safety disconnect device and vehicle‑mounted high‑power DC circuits. It provides reliable fast‑acting short‑circuit and over‑current protection for 500VDC automotive high‑voltage DC platforms.
Installation & Operating Notes
- Flush bolt‑on mounting; strictly follow M5 bolt torque 4.5±1.0 N·m to avoid bad contact & over‑heating risk.
- 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), perform rated‑current derating as per datasheet requirements.
- Parallel mounting 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 on fuse body.
- Additional reliability validation test shall be conducted for extremely high‑vibration vehicle working environments.
Packing & Supply
Standard bulk package. Sample testing support, OEM customization, stable mass‑volume supply for new‑energy vehicle & energy‑storage equipment manufacturers. REACH declaration available upon customer request.
