Bussmann FNQ‑R 15 Amp fuse 600 V

Bussmann FNQ‑R 15 Amp fuse: rugged time-delay protection for industrial circuits

The Bussmann FNQ‑R 15 Amp fuse is part of Eaton’s Limitron™ family, offering advanced Class CC, current‑limiting, time‑delay protection. Rated for 600 VAC and 300 VDC, it’s specially engineered to shield motor-driven loads, control transformers, and branch circuit equipment from overloads, while tolerating normal startup inrush currents.

What makes this fuse special?

At the heart of this fuse is its dual-element construction, designed to hold off hazardously high currents for short durations while responding instantly to sustained overloads or short circuits. During startup, the fuse tolerates up to 200 % of its rating for at least 12 seconds—preventing nuisance blows. Under fault conditions, it clears quickly to protect downstream gear.
