Key Features & Benefits
- aR fast‑acting square‑body DC fuse, up to ten‑times faster opening under high‑fault‑current for semiconductor‑level protection
- High‑interrupting capacity:50kA @1000VDC(L/R ≤3ms), minimum breaking current＞3In
- Low watt‑loss design; superior cycling capability, good anti‑voltaic‑impingement performance
- Excellent temperature tolerance; high mechanical shock & vibration resistance ≥20g acceleration
- Supports derating correction for high‑temperature, high‑altitude and forced‑air‑cooling operating‑conditions
- Two terminal versions available:C‑type and U‑type; comply with UL 248.13 & IEC 60269‑4; RoHS compliant, REACH document upon request
Application Overview
GFEVT1000‑36E‑1 series square‑body high‑speed fuses are purpose‑built for new‑energy heavy‑current DC‑systems. It provides reliable short‑circuit & over‑current protection for battery energy‑storage and power‑electronic devices.
Critical Tip: Long‑term operating current should be ≤75% of fuse rated‑current. Apply temperature / altitude derating factors for non‑standard working environment. Must cut‑off power before fuse replacement.
Installation & Operating Notes
- Select correct C‑type / U‑type terminal variant according to equipment mounting hole layout.
- Match copper conductor cross‑section per datasheet requirement; control terminal tightening torque to avoid over‑heating.
- Long‑term working current shall not exceed 75% of nominal fuse‑ampere rating.
- Apply derating correction when ambient temperature＞40℃ or installation altitude＞2000m.
- Fuse can mount vertically, horizontally or inclined; avoid gravity‑vibration interference for spring‑contact structures.
- Replace immediately if fuse body suffers mechanical damage; avoid live‑load fuse‑replacement unless equipment design permits.
Typical Applications
- Battery Energy‑Storage System(BESS) battery‑pack over‑current & short‑circuit protection
- DC relay and power‑semiconductor device backup short‑circuit protection
- Large‑capacity new‑energy DC power‑supply equipment protection
- Energy‑storage converter / inverter internal DC‑side protection
- Heavy‑current 1000VDC new‑energy industrial power‑distribution assemblies
Pair GFEVT1000‑36E‑1 fuse with our matching high‑power semiconductor fuse holders for complete heavy‑current DC‑protection assembly.
Safety Reminders
- Disconnect full DC power before servicing or replacing fuses. Strictly prohibit live‑line 1000VDC high‑voltage operation.
- Respect 75% rated‑current continuous‑working derating rule; extra derating needed for high‑temp / high‑altitude closed cabinet installation.
- Select correct breaking‑capacity matching system prospective short‑circuit‑current.
- Refer to official datasheet for I²t characteristic curve, derating curves and dimension drawings before mass‑procurement.
- Mechanically damaged fuse units must be discarded and replaced immediately.
