Bussmann FWH-80B High Speed Fuse

Ultra-Rapid Protection for Critical Semiconductor Circuits

Overview

The Bussmann FWH-80B High Speed Fuse delivers precision overcurrent protection for sensitive semiconductor devices and power electronics. Designed for extreme reliability, this fuse minimizes downtime by interrupting fault currents at unmatched speeds, safeguarding equipment like rectifiers, inverters, and motor drives from catastrophic damage.

Key Features

  • Ultra-Fast Response: Clears fault currents within milliseconds to protect vulnerable semiconductors (e.g., diodes, thyristors, IGBTs).
  • High Interrupting Rating: Withstands up to 200 kA (AC/DC), ensuring safety in high-energy applications.
  • Voltage & Current Ratings: Rated for 700V AC/DC systems and a nominal current of 80A.
  • Robust Construction: Ceramic body with precision sand filling enables stable performance under thermal stress and vibration.
  • Time-Current Precision: Engineered to operate faster than standard fuses, reducing arc energy and collateral damage.
  • Certified Safety: Compliant with international standards (UL/CSA, IEC, CE) for industrial use.

Applications

  • Power Conversion: Solar inverters, UPS systems, and rectifiers.
  • Industrial Electronics: Motor drives, welding equipment, and CNC machinery.
  • Transportation: EV charging stations, traction systems.
  • Renewable Energy: Wind turbine converters and battery storage protection.

Benefits

  • Minimize Equipment Damage: Prevents costly semiconductor failures by reacting faster than semiconductors can be destroyed.
  • Optimized System Uptime: Reduces maintenance interruptions with reliable, predictable operation.
  • Space-Efficient: Compact design (standard 10x38mm dimensions) fits densely packed panels.
  • Easy Replacement: Bolt-down terminals ensure secure installation and compatibility with existing holders.

Engineered for critical systems where speed is non-negotiable.
Trust Bussmann—the industry benchmark in circuit protection.
