DC Rated Fuses: Reliable Circuit Protection for High-Voltage Systems
When designing power systems for electric vehicles, renewable energy storage, or industrial equipment, DC Rated Fuses are your first line of defense against costly electrical faults. At Xi'an Green Power Technology, we engineer fuses that combine automotive-grade safety with cutting-edge thermal management—ensuring your high-voltage DC circuits stay protected under extreme conditions.
Product Overview
Our products are built to interrupt fault currents up to 20kA in milliseconds, safeguarding 48V–1500V DC systems in EVs, solar farms, and semiconductor equipment. With RoHS compliance and certifications like CE, TUV, and IATF 16949, they meet the strictest global standards for performance and environmental safety.

Why Our DC Fuses Stand Out?
1. Automotive-Grade Reliability
Designed for EV battery packs and charging piles, our fuses withstand rapid temperature shifts and vibrations common in electric mobility.
2. Custom Solutions in Days
Need a 150V/1kA fuse with blade terminals? Our 15-day prototyping ensures a perfect fit for your DC power systems.
3. Ultra-Fast Response
Proprietary arc-suppression tech reduces let-through energy by 40%, minimizing damage during short circuits.
4. Global Market Ready
Pre-certified to EU and North American standards, our DC fuse technology accelerates your product’s time-to-market.
Applications
- EV/HEV Systems: Protect battery modules and charging stations from overcurrent surges.
- Renewable Energy: Secure solar/wind ESS against DC arc faults.
- Industrial Robotics: Ensure uptime in automated 48V DC machinery.
- Semiconductor Equipment: Prevent costly downtime in high-precision manufacturing.
