Hi-Tech® Current-Limiting Fuses Standard
Fast, reliable current‑limiting protection for medium voltage distribution.
Safeguard essential electrical assets
ABB's Hi-Tech current-limiting fuses deliver reliable fault-clearing in less than half a cycle, reducing equipment stress and improving safety. With some of the industry's lowest let-through values and superior protection in a compact, cost-efficient form, Hi-Tech fuses minimize equipment damage. A patented damage sensor reduces fuse failure risk, while 100% factory testing helps ensure a long, reliable operating life in demanding conditions.
