Key Features & Benefits
- aR‑class partial‑range fast‑acting square‑body DC fuse, low I²t and powerful current‑limiting performance for semiconductor‑device backup short‑circuit protection
- High interrupting capacity:50kA @1000VDC; time constant ≤2±1 ms, minimum breaking current ≥3.0In
- Low watt‑loss, superior cycling capability, good temperature tolerance; vibration‑resistance ≥20g acceleration
- Supports derating correction for high‑temperature, high‑altitude and forced‑air‑cooling operating‑conditions
- Complies with UL 248.13, IEC 60269‑4; RoHS compliant, REACH documentation available upon export‑project request
Application Overview
GFEVT1000‑36 series square‑body high‑speed fuses serve as short‑circuit backup protection for new‑energy and industrial DC equipment. Widely used in EV / hybrid‑EV drive systems, supercapacitor modules, EV charging equipment, rail transit and marine power‑systems.
Critical Tip: Long‑term operating current shall be ≤75% of fuse rated‑current. Apply temperature‑altitude derating factors for enclosed cabinet working‑environments. Always cut‑off power before fuse replacement.
Installation & Operating Notes
- Mount fuse with specified installation torque:11.0±1.0 N·m to avoid abnormal over‑heating at terminals.
- Select copper conductor cross‑section according to datasheet requirement, guarantee stable contact performance.
- Long‑term continuous working current cannot exceed 75% of nominal fuse ampere rating.
- Implement current derating when ambient temperature＞40℃ or installation altitude＞2000 m in closed cabinets.
- Permitted for vertical, horizontal or inclined mounting; avoid gravity‑vibration interference for spring‑contact constructions.
- Replace immediately if fuse suffers mechanical damage; avoid live‑load fuse‑replacement unless equipment design permits.
Typical Applications
- Electric Vehicle & Hybrid‑EV drive‑system over‑current and short‑circuit backup protection
- Supercapacitor module power‑circuit protection
- EV charging equipment internal DC‑side protection
- Rail transit and marine vessel DC power‑system protection
- BESS energy‑storage equipment, converter‑inverter semiconductor‑device backup protection
Pair GFEVT1000‑36 series fuse with our matching heavy‑duty semiconductor fuse holders for complete high‑speed DC‑protection assembly.
Safety Reminders
- Disconnect full DC power before servicing or changing fuses. Strictly prohibit live‑line 1000VDC high‑voltage operation.
- Observe 75% rated‑current continuous‑working derating rule; extra derating required for high‑temp / high‑altitude enclosed‑cabinet installation.
- Select fuse breaking‑capacity higher than prospective short‑circuit‑current of your system.
- Refer to official datasheet for I‑t characteristic curve, derating curves and dimension drawings before mass‑procurement.
- Mechanically‑damaged fuse units must be discarded and replaced immediately.
