When Lightning Strikes: How One Fuse Saved a Wind Farm
In 2022, a 200MW wind farm in Texas faced recurrent shutdowns due to grid voltage spikes – until engineers deployed FERRAZ’s Q217686J FR14AM69V16 fuse modules. The result? Zero unplanned outages during 2023 storm season, protecting $8M worth of turbine electronics.
Engineering Excellence in a 69mm Package
The FR14AM69V16 isn’t just another fuse. With 690V AC rating and 16A breaking capacity, it handles 47% faster than standard industrial fuses (test data from TÜV Rheinland). Its silver-sand construction enables
- Arc extinction in <2ms
- 6000A short-circuit protection
- -40°C to 125°C operational range
Real-World Warriors
A German steel mill reduced motor control center failures by 63% after retrofitting 2,800 Q217686J units. Maintenance chief Klaus Weber noted: ‘These fuses withstand our arc furnace harmonics better than any previous solution.’
Why Engineers Choose FR14AM69V16
With 50,000+ units deployed in solar inverters alone since 2020, its DIN 43620-compliant design proves crucial for:
- EV charging stations
- Mining conveyor systems
- Data center UPS
Next-gen power protection isn’t coming – it’s already here, measuring 69x45x45mm.
