When Safety Meets Innovation
In 2023, a leading EV manufacturer reported 40% reduction in battery pack failures after adopting Zhongrong’s RS308-HB-4G-63A fuses. This 63A high-voltage fuse has become the silent protector for over 500,000 new energy vehicles globally.
Core Technology Breakdown
- 650V Rated Voltage: Withstands voltage spikes in fast-charging scenarios
- 100kA Breaking Capacity: 30% higher than industry average
- -40°C to 125°C operating range
Real-World Applications
In Shanghai’s 100MWh energy storage station, 2,800 RS308 units have maintained zero safety incidents for 3 consecutive years. ‘The ceramic-body design handles continuous current fluctuations perfectly,’ says Chief Engineer Wang.
Market Validation
Independent tests show:
• 3ms faster response than IEC 60269 standards
• 15,000+ mechanical vibration cycles passed
• 0.25mΩ typical resistance
As renewable energy installations grow 25% YoY, this fuse continues to protect critical infrastructure while enabling technological breakthroughs.
