Bussmann FWP-25B High Speed Fuse

Bussmann FWP-25B High Speed Fuse: Precision Circuit Protection

Overview
The Bussmann FWP-25B is a high-speed fuse engineered to deliver ultra-rapid overcurrent protection for sensitive electronic equipment and power semiconductor devices. Designed for demanding industrial applications, this 25-amp fuse safeguards critical circuits by interrupting fault currents within milliseconds, minimizing damage to expensive components like diodes, thyristors, and IGBTs.

Key Features

• Ultra-Fast Response: Clears short circuits in under 1 millisecond to protect vulnerable semiconductors from catastrophic failure.
• High Voltage Rating: Suitable for systems up to 700V AC/DC (verify specific voltage for your application).
• Precision Interruption: Features sand-filled ceramic body construction for reliable arc quenching and high interrupting capacity (up to 200kA).
• Compact Design: Space-efficient 10x38mm (0.4″ x 1.5″) form factor with blade terminals (FWP series standard). Ideal for tight panel spaces.
• Robust Build: Ceramic casing ensures thermal stability and durability in harsh environments (-50°C to +125°C).

Applications

• Power converters & inverters
• Motor drives and VFDs (Variable Frequency Drives)
• Renewable energy systems (solar/wind)
• Industrial UPS and battery protection
• Welding equipment

Compliance & Safety

• UL 248-14 listed
• IEC 60269-4 certified
• RoHS compliant

Why Choose FWP-25B?
Bussmann’s legacy in circuit protection ensures unmatched reliability. Engineered for precision, this fuse prevents costly downtime by isolating faults before they cascade through sensitive electronics. Always confirm compatibility with your system’s voltage and I²t requirements.

⚠️ Note: Replace only with identical specifications. Consult datasheet for derating guidelines.
