LLSRK005ID - 5Amp Fuse

LLSRK005ID - 5Amp Fuse

A blown fuse can stop equipment. Finding it quickly is the first step toward getting things running again. The Littelfuse LLSRK005ID 5A Class RK1 time-delay indicating fuse helps take the guesswork out of troubleshooting with an indicator window that darkens when the fuse opens. Designed for industrial and commercial electrical circuits, this Powr-Pro fuse combines a 5-amp current rating with 600V AC and 300V DC voltage ratings. Its time-delay characteristic helps you prevent unnecessary fuse openings during brief current surges, while precision-formed short-circuit elements provide current-limiting protection during electrical faults.
