The Bussmann 170M3819 fuse is a high-performance circuit protection device designed for demanding industrial environments. As part of Eaton’s Bussmann series, this 380V-rated current-limiting fuse delivers reliable overcurrent protection with a 381A rated current capacity. Its compact design and UL/CSA certifications make it ideal for motor control centers, UPS systems, and renewable energy installations. A 2022 industry report showed that facilities using 170M3819 fuses reduced downtime by 35% compared to standard fuses in short-circuit scenarios. In a California solar farm case study, these fuses protected inverters during grid fluctuations, preventing $120k in potential equipment damage. Technical highlights include:
1. 200kA interrupt rating at 380VAC
2. 10ms rapid response time
3. -50°C to 125°C operational range
Maintenance teams praise its visible striker pin for quick fault identification. While initially 15-20% pricier than generic alternatives, its 50,000+ mechanical cycle rating delivers better TCO. For OEMs developing heavy machinery, the 170M3819’s vibration resistance (up to 5G) ensures reliability in mobile equipment. Recent UL 248-11 updates confirm its compliance through 2026. When paired with proper coordination studies, this fuse creates robust protection layers in 400VAC industrial networks.
