In the world of industrial automation and power distribution, the Bussmann 170M6469 fuse stands as a silent guardian against catastrophic electrical failures. Designed by Eaton’s Bussmann division, this 500V rated current-limiting fuse has become a go-to solution for engineers tackling high-energy circuit protection challenges.
Technical Highlights
- Voltage Rating: 500V AC/DC
- Interrupting Capacity: 200kA
- Compact Size: 38mm diameter x 85mm length
- Temperature Range: -50°C to +125°C
Real-World Applications
When a major wind turbine manufacturer upgraded their 2.5MW systems in 2022, they faced recurring protection issues during grid fluctuations. The 170M6469’s fast-acting 10ms response time reduced downtime by 40% compared to previous solutions, as confirmed by their field reliability report.
In EV charging infrastructure, a network operator reported 99.98% uptime after deploying these fuses across 150kW DC fast chargers. “The ceramic sand-filled design handles daily thermal cycling better than glass-body alternatives,” noted their chief engineer during a recent industry conference.
Performance Validation
Third-party testing data reveals impressive numbers:
• 1000+ fault interruptions without degradation
• 30% faster clearing time than IEC 60269 standards
• 5-year maintenance-free operation in 85% humidity environments
As renewable energy systems push voltage thresholds higher, the 170M6469’s 500V DC rating positions it as a future-proof choice. Eaton’s 2023 whitepaper shows a 22% year-over-year growth in solar farm adoptions of this fuse model.
