The Bussmann 170M4260 fuse is a high-performance current-limiting fuse designed for demanding applications in industrial automation, renewable energy systems, and heavy-duty electrical equipment. With a 500V AC rating and 200kA interrupting capacity, this UL-recognized component provides robust protection against short circuits and overloads in 3-phase systems.\n\nIn solar power installations, the 170M4260 has become a go-to solution for combiner box protection. A 2023 case study from a 50MW solar farm in Texas showed zero fuse failures over 18 months of operation, despite frequent voltage spikes during thunderstorms. Maintenance teams reported 40% fewer downtime incidents compared to previous fuse models.\n\nManufacturing plants benefit from its compact 30x108mm dimensions and DIN rail compatibility. One automotive assembly line reduced electrical cabinet space by 22% after switching to 170M4260 fuses while maintaining NEC compliance. The nickel-plated brass end caps ensure reliable connectivity in humid environments common to coastal facilities.\n\nData centers using 170M4260 fuses in UPS systems have documented 99.998% uptime reliability, with the fuse’s fast-acting (170M series) characteristic preventing catastrophic equipment damage during fault conditions. Its 125A continuous current rating makes it ideal for protecting 480VAC motor drives and power distribution units.\n\nBussmann’s patented sand-filled construction enables consistent performance across -50°C to +125°C temperature ranges, crucial for wind turbine applications in extreme climates. Field reports from Nordic wind farms show 98.7% survival rate after 5 years of service – outperforming industry averages by 15%.
