Bussmann 170M6689 – Buss Semitron Fuse

Advanced Protection for Semiconductor Devices

The Bussmann 170M6689, part of the renowned Buss Semitron series, delivers exceptional overcurrent protection tailored for sensitive semiconductor components. Engineered for demanding industrial applications, this high-performance fuse safeguards critical equipment against short-circuits and overloads, ensuring operational reliability and minimized downtime.

🔑 Key Features:

  • Ultra-Fast Acting: Rapid response time (within milliseconds) to interrupt fault currents, preventing damage to semiconductors like diodes, thyristors, and IGBTs.
  • High Interrupt Rating: Withstands extreme fault currents up to 200 kA at 690V AC, offering robust protection in high-power environments.
  • Precision Design: Sand-filled ceramic body ensures arc quenching stability and consistent performance under stress.
  • Voltage & Current Ratings: Rated for 690V AC systems and a nominal current of 450A, ideal for medium-to-high voltage circuits.
  • Temperature Resilient: Operates reliably in temperatures from -50°C to +125°C, suited for harsh industrial settings.

🏭 Applications:

  • Motor drives and variable frequency drives (VFDs)
  • Uninterruptible Power Supplies (UPS) and inverters
  • Renewable energy systems (solar/wind converters)
  • Industrial rectifiers and welding equipment
  • Railway traction and power distribution systems

✅ Benefits:

  • Extended Equipment Lifespan: Prevents costly semiconductor failures by limiting thermal stress.
  • Compliance & Safety: Meets international standards (IEC 60269-4, UL 248-14) for semiconductor fuse performance.
  • Easy Integration: Compact, bolt-on blade design (e.g., 80x50mm dimensions) simplifies installation in fuse holders or assemblies.

Trust Bussmann’s legacy of innovation—choose the 170M6689 for unmatched protection where precision and durability matter most.

Note: Confirm voltage/current specifications with technical datasheets for application-specific requirements.
