Ultra Fast Fuses: Precision Protection for High-Energy Systems
In high-stakes electrical environments where milliseconds matter, ultra fast fuses are critical to safeguarding equipment and preventing catastrophic failures. At Xi'an Green Power Technology, we engineer these fuses to deliver unmatched speed and reliability for EV batteries, charging stations, and renewable energy systems. With a response time of <1ms, our solutions minimize damage during short circuits while meeting global safety standards like IEC 60269 and IATF 16949.
Product Description
The products act as the first line of defense in high-voltage circuits, interrupting fault currents before they escalate. Designed for DC applications up to 1,500V, our fuses feature ultra-low I²t values and advanced arc-suppression technology. Ideal for electric vehicles, solar inverters, and energy storage systems, they ensure operational continuity even under extreme thermal or electrical stress.

Why Our Ultra Fast Fuses Stand Out?
1. Automotive-Grade Reliability
Certified under IATF 16949/VDA6.3, our fuses meet stringent automotive standards for EV battery packs and charging infrastructure. They withstand vibrations, temperature swings, and humidity without performance loss.
2. Rapid Customization
Need a fuse tailored to your system's voltage or form factor? Our R&D team delivers prototypes in 2–4 weeks, adapting to specifications like blade-type designs or integrated thermal sensors.
3. Optimized for Renewable Energy
From solar inverters to wind turbines, our fuses handle DC surge currents and bidirectional power flows common in green energy systems.
4. Space-Saving Design
Compact yet powerful, our ultra fast fuses support miniaturized EV power distribution units without compromising breaking capacity.
Applications
- EV Battery Protection: Prevent thermal runaway in 400V–800V lithium-ion packs.
- DC Fast Chargers: Safeguard 1,000V+ charging stations from overloads.
- Solar/Wind Systems: Protect inverters against arc faults and grid surges.
- Energy Storage: Ensure safety in high-capacity battery banks.
Built on 20+ Years of Fuse Innovation
Our technical team—backed by experts from China XD Group and Xi'an Jiaotong University—pioneered breakthroughs like 500V/20kA water-cooled fuses. With ISO 9001-certified production and vertical integration, we combine legacy expertise with scalable manufacturing.
Quality Assurance
Every fuse undergoes rigorous testing, including:
- AEC-Q200 stress tests for automotive durability.
- UL 248-14 compliance for precise current-limiting performance.
- Final inspections to ensure ≤10 ppm defect rates.
