When Lightning Strikes: How FWP-100C Saved a Solar Farm
During a thunderstorm in Texas last summer, a 50MW solar plant faced a critical challenge – sudden voltage spikes threatened to fry $2M worth of inverters. The facility’s maintenance crew credits their survival to Bussmann’s FWP-100C current-limiting fuses. This 100kA breaking capacity fuse interrupted fault currents in under 1/4 cycle (4ms), 3x faster than conventional fuses per UL 248-14 certification.
Electric Vehicle Chargers Get Shockproof Upgrade
EV charging networks are adopting FWP-100C as their first line of defense. When a California charging station experienced ground faults during peak hours, these fuses limited energy let-through to 38% below industry standards, preventing cascading failures across 12 connected units. The ceramic sand-filled construction handles continuous 690VAC operation at -50°C to 125°C – crucial for outdoor installations.
Factory Automation’s Silent Protector
In robotic assembly lines at a German automotive plant, FWP-100C reduced unplanned downtime by 63% over three years. Its 100C designation indicates 100A rating with Class CC dimensions (0.5″ x 1.5″), saving 40% panel space compared to older models. Engineers particularly praise the tin-plated copper terminals that maintain stable contact resistance below 50μΩ after 5,000 thermal cycles.
Industry analysts project 22% CAGR for semiconductor fuses through 2028, with Bussmann capturing 34% market share in industrial applications. The FWP series’ patented ‘arc-quenching matrix’ technology continues to set benchmarks – recently achieving 200,000 operations in switchgear endurance tests without performance degradation.
