Mechanical Dimension
Square‑body construction, overall dimension 153±3 mm × 105±1.5 mm. 2‑pcs M12 mounting holes; max hole‑depth:12.5 mm, minimum thread‑length 12 mm. Terminals tin‑plated 3‑5 microns. Please check dimension drawing for full mechanical specifications.
Derating & Installation Instructions
- Recommended continuous operating current ≤ 75% of fuse rated‑current under standard‑5℃~40℃ ambient environment.
- For ambient temperature above 40℃, apply temperature‑derating factor Kt. For closed‑cabinet installation at altitude 2000‑4500 m, apply altitude‑derating Ka: derate 2‑5% per 1000‑meter elevation; open‑air deployment normally ignores altitude‑derating.
- Support vertical, horizontal and inclined mounting. Avoid gravity and vibration side‑effects for spring‑contact structures.
- Terminal contact resistance shall be kept low to prevent extra over‑heating and power‑loss rise.
Typical Applications
- Energy‑storage ESS container & DC main‑circuit protection
- Large‑capacity battery‑pack short‑circuit protection
- Wind‑power converter DC‑side protection
- DC drives and other 1500Vdc new‑energy power‑equipment over‑current & short‑circuit protection

Frequently Asked Questions
- What is rated voltage of GFEVT1500‑S‑105ES series?
- This high‑speed fuse is rated for 1500Vdc, designed for DC‑only new‑energy & energy‑storage circuits, not intended for AC‑system usage.
- What current ratings are available?
- 400A,500A,630A,700A,800A,900A,1000A,1100A,1200A,1250A,1300A,1350A,1400A,1500A,1600A,1800A,2000A (Size 4#).
- What is its interrupting capacity and fuse class?
- Interrupting capacity:50kA@1500Vdc(L/R ≤15ms); fuse class aR; minimum breaking current＞3 In.
- What standards and certifications apply?
- Designed per UL248‑13 & IEC 60269‑4; RoHS‑compliant; REACH declaration can be supplied upon request.
- What is the rule for continuous‑current selection?
- Keep continuous working current ≤ 75% of fuse rated‑ampere under‑5℃~40℃ standard ambient.
- Must I derate for high‑temperature or high‑altitude?
- Yes. Above 40℃ apply temperature‑derating Kt. For closed‑box installation 2000‑4500 m altitude derate 2‑5% /1000 m; open‑air application generally skips altitude‑derating.
- Can I install this fuse horizontally or inclined?
- Vertical, horizontal and inclined mounting are allowed. Prevent gravity and vibration from degrading spring‑contact electrical connections.
- What are main target‑applications?
- ESS energy‑storage systems, battery‑pack, wind‑power converters,DC‑drives and other 1500Vdc new‑energy power‑equipment short‑circuit protection.
- Can I replace the fuse under live‑load?
- Do NOT replace fuse while carrying live‑load unless a matched fuse‑disconnector switch assembly is implemented.
- What are the storage conditions?
- Store in original package:‑40℃~+85℃, RH ≤70% at 40℃, dust‑free warehouse environment.
