But not every surge of electrical current signals a problem. Motors need extra power to start, transformers experience temporary inrush currents when energized, and other inductive equipment can briefly draw more current than during normal operation. Part of the Littelfuse POWR-PRO™ family, this dual-element, current-limiting fuse combines time-delay operation with high interrupting capacity to protect your valuable equipment without unnecessary interruptions during normal startup.\u003c\/p\u003e\n\u003cp\u003eRated for 150 amps, 250V AC, and 125V DC, the LLNRK150 is well suited for appropriately rated industrial and commercial electrical systems, including service entrance equipment, main distribution circuits, feeders, and general-purpose branch circuits. Its two-element construction includes a thermally reversible, spring-loaded thermal overload element that helps accommodate temporary inrush currents while responding to sustained overload conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e150 Amp Continuous Current
