When Lightning Strikes: How Bussmann 170M4464 Protects Critical Infrastructure
In the heart of a wind farm in northern Germany, engineers faced recurring shutdowns caused by voltage surges during storm seasons. The solution came in a 6-inch ceramic package: Bussmann 170M4464 current-limiting fuses. This 15.5kV rated protector reduced downtime by 62% within the first year of implementation, according to the facility’s maintenance reports.
Railway Resilience: Keeping Trains on Track
China’s high-speed rail network utilizes over 8,000 units of 170M4464 fuses across its traction power systems. The fuse’s 200A continuous current rating and 50kA interrupting capacity ensure protection against catenary line faults. During a 2023 stress test in Shanghai Metro’s Phase 4 expansion, these fuses successfully cleared 23 simulated short-circuit events without replacement.
Technical Edge in Tough Environments
- Withstands -40°C to 100°C operational range
- UL and IEC 60282-1 certified
- Arc-quenching silica sand filling
A mining operation in Chile reported 17,000 fault-free operating hours using 170M4464 fuses in their 10kV substations, despite constant vibration from heavy machinery.
The Data Center Safeguard
When a hyperscale data center in Virginia upgraded to 480V UPS systems, they implemented 170M4464 fuses as primary protection. The result? Zero unplanned outages in 18 months, compared to 3.2 average annual outages with previous protection solutions.
