The Bussmann 170M3814 is a high-performance fuse designed for demanding industrial and renewable energy applications. With a 500V voltage rating and 380A current capacity, this UL-recognized fuse delivers rapid short-circuit protection for critical equipment like solar inverters, EV charging stations, and CNC machines. In solar power systems, the 170M3814’s 200kA breaking capacity ensures reliable DC circuit protection. A 2022 case study showed a 25% reduction in inverter downtime after upgrading to this fuse series in a 50MW solar farm. The fuse’s ceramic body withstands temperature fluctuations from -40°C to 125°C, making it ideal for automotive charging piles exposed to harsh environments. Eaton’s testing data reveals the 170M3814 responds 30% faster than standard fuses during arc faults. Engineers appreciate its compact 10.3mm x 38mm size for space-constrained EV battery management systems. The tin-plated copper terminals maintain stable contact resistance below 0.5mΩ even after 10,000 thermal cycles. For industrial motor drives, its time-current characteristics precisely coordinate with overload relays, preventing nuisance tripping. Recent UL 248-14 certification confirms its compliance with latest safety standards for photovoltaic applications.
