Hi-Tech® Valiant™ Current-Limiting Fuses

Fire‑mitigating, high‑performance full‑range fuse technology.

Protect what matters most

ABB's Hi-Tech Valiant current-limiting fuses are purpose-built for fire mitigation. Combining over 20 years of field-tested Hi-Tech fuse technology, the hermetically sealed design contains expulsive showers during fuse operations, preventing debris from falling on dry vegetation and potentially igniting a wildfire. Fully compliant with California Code of Regulations, Title 14, Section 1255(10), the fuses are a reliable solution for utilities and crews working in high fire-risk environments.
