FAQ
1: What does aR‑class mean for GFEVF150 fuse?
A: aR stands for semiconductor‑protection fuse class. In fact, it provides ultra‑fast short‑circuit cut‑off, which can limit fault energy and prevent permanent damage to sensitive power semiconductors such as IGBT and thyristor.
2: Can GFEVF150 series be used for AC‑circuit protection?
A: This series is optimized for DC‑system scenarios. For this reason, do not apply it to AC circuits unless you complete full‑performance verification together with manufacturer technical support.
3: Why limit continuous operating current ≤75% of rated value?
A: This setting reserves thermal safety margin for ambient‑temperature rise, altitude derating and transient load fluctuation. It can extend fuse service‑life and avoid unexpected non‑intentional blowing.
4: What derating rules apply when installing above 2000 m altitude?
A: For closed cabinet installation, derate rated‑current 2%‑5% per every 1000‑meter elevation increase. Meanwhile check air‑insulation clearance reduction. In open‑air environment, users can generally skip derating operations.
5: Is parallel connection allowed to obtain higher‑current capacity?
A: Yes, parallel mounting is permitted under official specification guidelines. But users must guarantee well‑balanced current‑sharing for each fuse unit in system design.
6: Does high ambient temperature affect fuse rated‑current?
A: Yes. If ambient temperature exceeds +40℃, you need to adopt temperature‑derating factor Kt to reduce practical working‑current. Please check the derating curve in datasheet for exact values.
7: Am I allowed to replace fuse under live‑load condition?
A: Normally you cannot replace fuse with load connected. Unless your device belongs to special load‑break fuse‑switch, please cut off power supply before any fuse‑replacement work.
