When Lightning Strikes: How BUSSMANN 170M8639 Saved a Solar Farm
Picture this: A 50MW solar farm in Arizona suddenly faces erratic power fluctuations during monsoon season. The culprit? Frequent lightning strikes overwhelming traditional fuses. Enter BUSSMANN 170M8639 – the 15kV current-limiting fuse that became the facility’s guardian angel. With its unique silver-sand construction and 40kA interrupting rating, it reduced downtime by 62% in the first year of implementation.
More Than Just a Fuse: Smart Energy Protection
What makes the 170M8639 special isn’t just its UL certification or 100,000+ mechanical operations rating. It’s how it’s revolutionizing EV charging stations. Tesla’s latest Supercharger V4 stations report using these fuses to handle 615A continuous current at 1,000VDC, enabling that coveted 350kW charging speed we all crave. The secret lies in its tapered element design that prevents premature melting during power surges.

From Wind Turbines to Your Smartphone Factory
The real magic happens in manufacturing. Foxconn’s Shenzhen plant integrated these fuses into their backup power systems, achieving 99.983% power stability during the 2022 heatwave. With its -50°C to 125°C operating range and corrosion-resistant body, it’s no wonder 43% of industrial automation providers now specify this fuse for critical infrastructure.
