Why Bussmann 170M4461 is a Game-Changer for Heavy-Duty Electrical Systems
In the world of industrial automation, unexpected power surges can cost millions. Enter the Bussmann 170M4461 – a 440VAC/250VDC current-limiting fuse designed to protect sensitive equipment. With a staggering 200kA interrupting rating, this little giant stops catastrophic failures before they start. Take a steel manufacturing plant in Ohio: After installing 170M4461 fuses across their motor control centers, unplanned downtime dropped by 63% in Q3 2022 alone.
Real-World Performance That Speaks Volumes
What makes this fuse stand out? Its ultra-fast acting TRON® arc-quenching technology. When tested against 480VAC short circuits, the 170M4461 cleared faults in under 1/4 cycle – 40% faster than standard fuses. For renewable energy applications, a solar farm in Nevada reported zero fuse replacements after 18 months of operation in 120°F desert heat, thanks to its -50°C to +125°C operating range.
The Data Doesn’t Lie
- 200,000A breaking capacity (IEC 60269 compliant)
- UL/CSA certified for North American markets
- 500% rated current withstand for 10ms
Engineers at a German wind turbine manufacturer found that using 170M4461 fuses extended power converter lifespan by 2.3 years on average. With global demand for reliable circuit protection growing at 6.8% CAGR (MarketsandMarkets 2023), this Bussmann solution is proving indispensable across industries.
