응용 시나리오

GFEVT500‑series fast‑acting high‑speed ev dc fuse 500VDC 10‑400A is designed for new‑energy transportation and energy‑storage markets: EV / HEV battery‑pack protection, DC relay backup protection, maintenance safety disconnect device, 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 specified bolt torque value for each model to avoid poor 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), implement rated‑current derating in accordance with datasheet requirements.
• 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 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.
