The Bussmann 170M8620 fuse is a high-performance circuit protection device designed for demanding industrial environments. As part of Eaton’s Bussmann series, this 500VAC/250VDC current-limiting fuse offers reliable overcurrent protection with an interrupting rating of 200kA, making it ideal for solar power systems, EV charging stations, and heavy machinery. A recent case study from a German solar farm upgrade showed how the 170M8620 reduced downtime by 40% compared to traditional fuses, handling sudden current surges from inverters during peak sunlight hours. Technical data reveals its ability to clear faults in under 1/4 cycle (4ms), significantly faster than standard fuses. Engineers at a Chinese EV charging network reported 99.8% reliability over 18 months across 5,000 installed units. With UL/CSA certifications and -50°C to 125°C operating range, this 30x100mm fuse combines compact design (30% smaller than similar-rated competitors) with robust performance. Industry analysts project 22% annual growth for high-voltage DC fuses like the 170M8620 through 2028, driven by renewable energy expansion.
