Motors, transformers, and other inductive loads can draw much more current during startup than once they're running. The challenge? Protecting those circuits against dangerous overloads and short circuits without having a fuse open every time equipment starts. The Littelfuse LLNRK175 175 Amp Class RK1 time-delay fuse is engineered to handle that balance. As part of the Littelfuse POWR-PRO™ series, it combines dual-element time-delay operation with exceptional current-limiting performance to help safeguard electrical equipment while reducing unnecessary interruptions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e175 Amp Continuous Current
