The last thing you want is a blown fuse bringing everything to a halt when nothing is actually wrong. That's where the Littelfuse LLNRK070 70 Amp Class RK1 time-delay fuse comes in. Part of the Littelfuse POWR-PRO™ series, this dual-element fuse tolerates temporary startup currents while providing dependable protection against sustained overloads and short circuits.\u003c\/p\u003e\n\u003cp\u003eMeanwhile, low-resistance construction helps limit power losses during everyday operation. The fuse also features a thermally reversible, spring-loaded overload element that provides time-delay performance without unnecessary openings during normal inrush conditions, helping maintain an older electrical installation. The Littelfuse LLNRK070 time-delay fuse can also be installed in compatible existing Class H fuse blocks, improving short-circuit protection in systems that previously used lower-interrupting-rating Class H fuses. From motor control equipment to service entrance and feeder circuits, the LLNRK070 delivers the kind of protection that helps keep electrical systems working as intended.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e70 Amp Continuous Current
