LLSRK070ID - 70 Amp Fuse

LLSRK070ID - 70 Amp Fuse

When your fuse blows, the last thing a maintenance crew needs is a long search for the problem. The Littelfuse LLSRK070ID helps remove some of that guesswork from troubleshooting. Its built-in indicator window darkens when the fuse opens, making it easier to spot the affected fuse and get to work. Part of the Littelfuse POWR-PRO LLSRK_ID series, this 70-amp Class RK1 fuse offers time-delay protection for industrial electrical circuits. It can handle temporary current surges without opening unnecessarily, while its precision-formed short-circuit elements help protect equipment during electrical faults.
