Application Overview
450‑1500V new‑energy charging and energy‑storage systems require dedicated semiconductor high‑speed fuse protection. GFEV/400E fuse holder shall be matched with qualified semiconductor / high‑speed fuse links according to actual system voltage, current and short‑circuit parameter.
Critical Tip: Always select fuse links whose breaking capacity exceeds system short‑circuit current. Follow M8 screw torque requirement from official datasheet during installation.
Installation Steps
- Securely mount the fuse holder onto equipment mounting plate.
- Connect heavy‑power conductors to M8 screw terminals, tighten to torque value specified on datasheet.
- Insert correctly‑rated semiconductor / high‑speed fuse link.
- Double‑check terminal tightness and mechanical fixation status.
- Contact sales team for custom requirements upon bulk‑order placement.
Typical Applications
- New‑energy charging pile internal high‑power circuit protection
- Battery Energy Storage System (BESS) high‑current DC feeder protection
- High‑power DC power‑supply equipment protection
- Industrial high‑power converter and inverter protection
- New‑energy heavy‑current power‑equipment protection assemblies
Pair this GFEV®‑400E fuse holder with our matching semiconductor high‑speed fuses for complete heavy‑current new‑energy AC‑DC protection assembly.
Safety Reminders
- Cut‑off all AC and DC power before fuse replacement. Strictly prohibit live‑line high‑voltage operation.
- Observe datasheet‑specified torque for M8 screw terminals; insufficient torque will trigger abnormal over‑heating under full‑load heavy‑current condition.
- Must adopt qualified semiconductor / high‑speed special fuses; ordinary general‑purpose fuses cannot be used for new‑energy high‑power equipment.
- Refer to official datasheet dimension drawings and electrical parameters before mass‑procurement.
