The challenge is protecting that equipment from dangerous overloads and short circuits without interrupting power every time a motor or transformer switches on. That's where the Littelfuse LLNRK090 90 Amp Class RK1 time-delay fuse comes in. Part of the Littelfuse POWR-PRO™ LLNRK series, this dual-element fuse delivers strong current-limiting protection while allowing the brief inrush currents common to industrial and commercial equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e90 Amp Continuous Current
