Application Scenarios

GFEVT1000‑59E Series Square‑Body Fast‑Acting aR DC Fuse 1000VDC 100‑800A applies to high‑voltage DC new‑energy projects. Suitable for energy‑storage power‑station cabinets, battery‑pack protection, maintenance safety disconnector and DC relay backup short‑circuit protection. aR‑class fast‑acting characteristic offers reliable fault‑current protection for power semiconductors and DC‑side power components.

Installation & Operating Notes

• Size 2# square‑body; select B‑bolted horizontal or K‑hook‑fork vertical terminal version according to cabinet layout; apply specified bolt torque to avoid poor contact and over‑heating risk.
• Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating‑factor Kt for ambient temperature above 40℃.
• Altitude ≤2000m no‑derating; closed‑box installation between 2000‑4500m: derate 2%‑5% rated‑current per 1000m elevation increase. Open‑air installation normally ignores altitude impact. Re‑check insulation clearance at high altitude in compliance with GB/T16935.1.
• Supports vertical, horizontal and inclined mounting; for spring‑contact‑type devices, prevent gravity‑vibration negative influence over electrical contact performance.
• Forced‑air cooling improves heat dissipation and increases allowable operating current, refer to Kv correction coefficient.
• Do NOT replace fuse under live DC load unless equipped with certified load‑break switchgear.
• Replace fuse immediately if shell crack, deformation or mechanical damage appears.
• Additional reliability validation test required for extremely high‑vibration industrial environments.
• Select matched copper conductor cross‑section for terminals to control temperature‑rise.
• Ordering note: clarify terminal type B(bolted) or K(hook‑fork customized) when placing purchase order, electrical performance is identical for two versions.
