When Safety Meets Speed
In Shenzhen’s bustling EV charging stations, engineers recently upgraded 200+ charging piles with BUSSMANN 170M1572 fuses. The result? A 67% reduction in overcurrent incidents during summer peak hours. This 500VDC rated fuse with 150A breaking capacity has become the silent protector of China’s new energy infrastructure.
Precision Engineering in Action
Unlike traditional fuses that take 5-10ms to react, the 170M1572 achieves sub-2ms interruption speeds. Its silver-plated terminals maintain contact resistance below 0.15mΩ even after 10,000 thermal cycles. For battery pack manufacturers like CATL, this translates to 0.03% failure rate in 2023 field data – 4X better than industry average.
Real-World Impact
Shanghai Metro’s new Line 14 uses these fuses in its 1500V traction power system. During simulated short-circuit tests, the 170M1572 limited arc energy to 12kJ – 38% lower than comparable solutions. Maintenance chief Zhang Wei notes: ‘We’ve extended preventive maintenance intervals from 6 to 9 months since adoption.’
The Future-Proof Choice
With 93% efficiency retention after 100,000 operations and UL/CE/IEC certifications, BUSSMANN’s innovation is powering everything from 5G base stations to offshore wind farms. As renewable energy grows 40% annually in Asia-Pacific, this 1572-series fuse proves that millimeter-sized components can megawatt-level differences.
