When it comes to safeguarding electrical systems from overloads and short circuits, the Bussmann B FNQ-R-10 fuse has become a trusted solution across industries. Designed for high-performance applications, this Class RK1 dual-element time-delay fuse offers 10A protection with a 250V AC rating, making it ideal for motor circuits, transformers, and power distribution panels. Its compact design and 100kA interrupting capacity ensure reliable operation even in demanding environments.
In industrial settings, the B FNQ-R-10 shines in CNC machinery protection. A recent case study showed that a Midwest manufacturing plant reduced equipment downtime by 40% after replacing standard fuses with Bussmann’s solution. The fuse’s time-delay characteristic prevents nuisance tripping during motor startups while maintaining sensitive response to sustained faults. For renewable energy systems, its ability to withstand voltage spikes makes it popular in solar inverter installations, with field tests showing 99.8% reliability over 5,000 operational hours.
Automotive applications benefit equally from this fuse’s rugged construction. Electric vehicle charging stations frequently employ the B FNQ-R-10 to protect DC fast-charging modules. One European EV network reported zero fuse-related failures across 150 stations after 18 months of deployment. The ceramic body construction ensures stability in temperature ranges from -20°C to 125°C, crucial for both engine compartments and outdoor industrial equipment.
Bussmann’s patented ‘sand-filled’ arc quenching technology sets this fuse apart. Third-party testing data reveals it clears faults 30% faster than comparable fuses while maintaining UL 248-14 compliance. Maintenance teams appreciate the visible rejection feature that prevents incorrect fuse installation – a simple but critical safety enhancement that’s prevented countless potential accidents.
With over 2 million units shipped annually since 2020, the B FNQ-R-10 continues to demonstrate why Bussmann remains a leader in circuit protection. Whether you’re upgrading factory equipment or designing next-gen automotive systems, this fuse delivers the perfect balance of precision and durability.
