When Machines Need a Bodyguard, This Fuse Steps Up
In the heart of Detroit’s automotive production line, a 480V motor control center experienced 27 unexpected short circuits last year. The culprit? Inferior fuses that couldn’t handle inrush currents. Enter the BUSS KTK-25 – after installation, downtime reduced by 68%.
Precision Protection for Heavy-Duty Operations
This 600V/25A time-delay fuse isn’t just metal and ceramic. Its patented ‘dual-element’ design combines thermal and magnetic protection, allowing 500% overload tolerance for 10 seconds – critical for motor startups. Phoenix manufacturing plant reported 412 consecutive days of spike-free operation after switching to KTK-25.
Real-World Warrior: Wind Turbine Application
At Wyoming’s Chugwater Wind Farm, 62 KTKs protect pitch control systems. During a 2023 lightning storm, they absorbed 18kV surges without failure – a feat that saved $2.3M in potential generator damage.
Why Engineers Keep Coming Back
- 200kA Interrupt Rating – handles worst-case scenarios
- UL 248-14 & IEC 60269-4 certified
- 22% faster clearing time than competitors
Maintenance supervisor Gina Torres notes: ‘We’ve cut fuse replacement frequency from quarterly to biennial. The ceramic body resists vibration cracks that plague glass fuses.’
Future-Proofing Power Networks
As EV charging stations proliferate, the KTK-25’s DC compatibility (up to 250V) makes it ideal for 150kW fast chargers. Sacramento’s new charging hub uses 340 units, achieving 99.98% uptime in Q1 2024.
