LLNRK060 - 60 Amp Fuse

LLNRK060 - 60 Amp Fuse

A motor kicks on, the current jumps for a moment, and everything should keep running. But with the wrong fuse, that normal startup surge can cause an unnecessary shutdown. The Littelfuse LLNRK060 60 Amp, 250V Class RK1 time-delay fuse is designed for electrical systems where brief current surges are part of the job. Rated for 60 amps, 250V AC, and 125V DC, the LLNRK060 suits a wide range of industrial and commercial electrical applications. Littelfuse lists AC interrupting ratings of 200,000A and 300,000A at 250V AC, plus a 20,000A interrupting rating at 125V DC. The fuse also features low-resistance construction to help minimize power losses during normal operation. Whether you're maintaining motor circuits, protecting transformers, or working on a facility's electrical distribution system, the Littelfuse LLNRK060 time-delay fuse handles everyday startup demands while protecting equipment when something goes wrong.
