The BUSSMANN 170M6469 fuse has become a go-to solution for engineers seeking reliable circuit protection in demanding environments. With a 690V AC/DC voltage rating and 630A current capacity, this UL/CSA-certified current-limiting fuse delivers exceptional performance in industrial power distribution systems. Its unique silver-sand construction ensures rapid arc quenching, achieving interruption speeds under 8ms – 40% faster than conventional fuses. A recent case study at a solar inverter facility showed how replacing legacy fuses with 170M6469 units reduced downtime by 62% during grid fault conditions. The fuse’s compact 104mm length makes it ideal for space-constrained panels, while its 200kA breaking capacity handles worst-case short circuits. Maintenance teams particularly appreciate the visible striker pin indicator, which simplifies fault identification without requiring disassembly. In EV charging station deployments, the 170M6469’s ability to withstand temperature fluctuations (-50°C to +125°C) has proven critical for outdoor installations. Industry data shows a 98.7% survival rate after 10,000 operational cycles, outperforming competitors by 15-20%. For engineers designing robust protection systems, this fuse combines proven reliability with measurable performance advantages.
