Mechanical Dimension
Square housing structure, nominal width 159mm, max 163mm. Each side fitted with 5pcs M12 mounting holes; Hole max depth:13mm, minimum thread length:10mm. Terminals tin‑plated 3‑5μm. Refer to dimension drawing for full mechanical dimension details.
Derating & Installation Instructions
- Recommended continuous working current ≤75% of fuse rated‑current under standard environment.
- When ambient temperature higher than 40℃, apply temperature derating factor Kt. For closed cabinet high‑altitude installation 2000‑4500m, apply altitude factor Ka, derate 2‑5% per 1000‑meter elevation.
- M12 mounting nut recommended tightening torque: 35±4% N·m.
- Support vertical, horizontal and inclined installation; prevent gravity and vibration influence for spring‑contact assembly.
Typical Applications

Frequently Asked Questions
- What is the rated voltage of GFEVT1500‑159E series fuse?
- This series is rated for 1500Vdc, designed exclusively for DC new‑energy systems, not recommended for AC application.
- What current range does GFEVT1500‑159E cover?
- Available rated current: 1400A,1500A,1600A,1800A,2000A,2500A,3000A.
- What is the interrupting capacity?
- 250kA@1500Vdc (L/R ≤5ms); 100kA@1500Vdc (L/R ≤15ms).
- What certifications does this fuse have?
- UL Listed to UL248‑13 standard, RoHS compliant. REACH declaration available upon customer request.
- What continuous current should I use for selection?
- General rule: continuous operating current ≤ 75% of fuse rated current under standard ‑5℃~40℃ ambient condition.
- Do I need derating for high‑temperature or high‑altitude installation?
- Yes. Above 40℃ ambient temperature needs temperature derating factor Kt. For closed‑box installation between 2000‑4500 m altitude, derate rated‑current 2‑5% per 1000 m rise. Open‑air installation can ignore altitude influence generally.
- What is the correct tightening torque for M12 mounting screws?
- Recommended nut tightening torque: 35±4% N·m. Improper torque will cause overheating and higher power loss.
- Can this fuse be installed horizontally or vertically?
- Yes, supports vertical, horizontal and inclined mounting. Avoid gravity & vibration impact for spring‑contact connections.
- What applications fit for GFEVT1500‑159E high‑speed fuse?
- Energy storage ESS container, large battery pack, DC combiner cabinet, 1500Vdc converter, new‑energy power station DC short‑circuit & over‑current protection.
- Can I replace the fuse under load condition?
- NOT recommended. Do not replace fuse with live‑load unless matched fuse‑disconnector switch assembly is applied.
- What is storage requirement?
- Store in original package: ‑40℃ ~ +85℃, max RH 70% at 40℃, dust‑free warehouse environment.
