Bussmann 120 Vsc Super-Lag Real Links 250V Twenty Fusible Link

The Bussmann LKN-20 Super-Lag Renewable Fuse Link is a 250 VAC, 20 A fuse element designed to pair with REN-20 Class H/K5 2-inch L fuse blocks, providing a field-replaceable protection option for feeders and power circuits. As a renewable fuse link, it is non-current-limiting and time-delay (slow-blow), allowing temporary surges to pass while still protecting against persistent overcurrent conditions. The 2-inch L-form body fits standard REN-20 assemblies, and when the fuse element opens, only the LKN-20 link needs replacement, enabling quick servicing without discarding the entire protective assembly. Manufactured by Bussmann (an Eaton brand) and sold under the REN-20 family, this component serves as the replaceable element within a compact protection scheme, offering repeatable maintenance in systems that require a reliable, field-serviceable fuse link.
