Littelfuse, Inc. UL Class RK1 Dual Element Time-Delay Fuse LLSRK04.5

Description
Littelfuse LLSRK series POWR-PRO™ fuses provide superior overload and short circuit protection for service entrance, main, feeder and general-purpose branch circuits up to 600 amperes.LLSRK series fuses can be installed in existing Class H fuse blocks to upgrade systems containing lower interrupting rating Class H one-time or renewable fuses. Extremely current limiting, which reduces damage to circuits and equipment 300 kA interrupting rating Current-limiting performance permits use of less-costly equipment and low resistance reduces power consumption Two-elements, including a thermally reversible spring-loaded thermal overload element, ensures excellent time delay for minimal nuisance opening
