Bussmann FWP-30B High Speed Fuse

Precision Protection for Critical Electronics

Overview

The Bussmann FWP-30B High Speed Fuse delivers ultra-rapid circuit protection for sensitive semiconductor devices and power electronics. Designed for 700V AC/250V DC applications, this 30-amp fuse interrupts fault currents within milliseconds to safeguard equipment like rectifiers, inverters, and motor drives from damaging overcurrent surges.

Key Features

  • Extreme Speed: Clears faults in ≤1/4 cycle (4 ms) to prevent thermal damage to semiconductors
  • High Voltage Rating: 700V AC / 250V DC operational voltage
  • Precision Protection: 30A current rating with low I²t let-through energy
  • Robust Construction: Ceramic body with quartz sand filler for reliable arc quenching
  • High Interrupt Capacity: 200kA IR (interrupting rating) at 700V AC
  • Universal Compatibility: UL 248-14 / IEC 60269-4 certified, RoHS compliant

Applications

  • Semiconductor Protection: Diodes, SCRs, IGBTs, and thyristors
  • Power Conversion: Industrial rectifiers, UPS systems, DC drives
  • Renewable Energy: Solar inverters, wind turbine converters
  • Transportation: EV charging stations, railway traction systems
