Bussmann FNQ-R-12 Eaton Bussmann series FNQ-R fuse, 12 A, Class CC, Non-indicating, Ferrule end x ferrule end, 12 sec at 200%, 200 kAIC, Melamine tube, Standard, 600 V

Description

Features

• Featuring a specialized rejection tip, this Class CC fuse is mechanically designed to fit exclusively into code-compliant Class CC fuse blocks and holders. This physical constraint prevents field technicians from accidentally replacing it with standard $10 \times 38\text{ mm}$ midget fuses, ensuring your critical control circuits retain their high-interrupting safety margins and localized protection.
• Engineered with a built-in time-delay mechanism, this fuse tolerates momentary, high-magnitude current surges up to 10 times its 0.5-amp rating during inductive equipment startup. This deliberate delay eliminates frustrating, costly downtime caused by false trips while providing tight, reliable overcurrent protection against sustained overloads and short circuits.
• Boasting a robust 600V AC maximum rating, this component is purpose-built to safeguard demanding industrial control branches, automation panels, and commercial HVAC equipment. It effectively handles standard industrial distribution voltages, shielding sensitive components like contactor coils and control transformers from catastrophic electrical failure.
• With an exceptional interrupting capacity of 200kA RMS Symmetrical at 600V, this fuse provides a massive defensive barrier against violent electrical faults. Its extreme current-limiting design stops damaging fault currents in their tracks within milliseconds long before they can warp busbars, rupture enclosures, or damage downstream components.
