<h2>Overview</h2>
<p>The <strong>Bussmann FNA-6/10</strong> is a pin-indicating, dual-element time-delay supplemental fuse rated 6/10A at 250V AC. Manufactured by Eaton’s Bussmann division, this cartridge fuse is engineered for circuits requiring protection against high inrush currents and transient overcurrent conditions. The FNA-6/10 combines melamine tube construction with nickel-plated ferrule ends for reliable electrical contact and durability. This lot contains 9 new, unused units—ready for immediate installation in control panels, power distribution systems, and equipment requiring IEEE 1815 (Class 5AG/AB) supplemental protection.</p>
