Why Our 250A NH Fuse Stands Out?
1. Industrial-Grade Durability
Withstand vibrations, dust, and humidity in CNC machinery, EV battery packs, or offshore wind turbines. The ceramic housing and arc-quenching filler ensure stable operation over 100,000 mechanical cycles.
2. Precision Protection for Renewable Energy
Specifically optimized for solar inverters and energy storage systems (ESS), our 250A NH Fuse minimizes downtime caused by DC arc faults or PV array surges.
3. Fast Global Compliance
Pre-certified to UL (North America), CE/TUV (Europe), and CCC (China), reducing lead times for OEMs launching machinery or solar projects worldwide.
4. Customizable Designs
Need a slimmer profile for robotic arms or higher DC voltage ratings? Our R&D team adapts terminal configurations, coatings, and specs within 4–6 weeks.
Applications
- EV/Charging Infrastructure: Protect battery management systems (BMS) and DC fast chargers.
- Solar/Wind Farms: Isolate faults in 1500V DC strings or grid-tie inverters.
- Industrial Panels: Safeguard motor drives, CNC machines, and semiconductor equipment.
Trusted by Global Manufacturers
With 20+ years of expertise in high-current protection, we've partnered with automotive and renewable energy leaders to:
- Achieve IATF 16949 compliance for EV-grade reliability.
- Develop the 500V/20kA water-cooled fuse (2018) for hybrid machinery.
- Maintain a 98% consistency rate via automated production lines.
FAQs
Q: Can the product handle bidirectional currents in EV regenerative braking?
A: Yes. Our NH-CB series supports bidirectional energy flow up to 30kA, tested per IEC 60269-4.
Q: What certifications apply to European solar projects?
A: The NH-PV series is TUV-certified (EN 60269-6) and REACH-compliant for EU markets.
Q: Do you provide surge protection data for solar applications?
A: Yes. Request our I²t let-through energy reports (≤20kA²s) via fusemaker@163.com.
Q: What's the lead time for 10,000 units?
A: Stocked GFZ series orders ship in 15 days; custom designs take 4–6 weeks.
