With the ability to handle temporary inrush currents — such as those common when motors start, or transformers energize — this fuse helps prevent annoying nuisance trips while still guarding against dangerous overloads and fault conditions. Its dual-element design ensures fast response to serious short circuits without sacrificing tolerance to normal startup surges. Engineered with a 200 kAIC interrupting rating, the ECNR30 stands ready to protect your circuits even under demanding fault-current events. Plus, with straightforward ferrule‑end connections and standard voltage ratings, installation is simple and versatile across a variety of electrical systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual‑Element Time‑Delay Design:\u003c\/strong\u003e Allows you to size the fuse closer to the actual running current of motors and transformers, which reduces costs and still protects equipment effectively.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Capacity:\u003c\/strong\u003e A 200 kAIC rating ensures the fuse can safely clear high fault currents, offering dependable protection under stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Voltage Compatibility:\u003c\/strong\u003e Rated for up to 250 V AC and 125 V DC, enabling use across many common commercial and industrial electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Installation:\u003c\/strong\u003e Ferrule‑end terminals make for easy, secure connections, minimizing hassle during setup or maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced Protection:\u003c\/strong\u003e The time-delay feature tolerates harmless inrush surges while instantly reacting to real overloads or short circuits — a trustworthy balance of flexibility and safety.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 30 Amp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250 V AC \/ 125 V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity:\u003c\/strong\u003e 200 kAIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e ~8 seconds at 500% of rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Construction:\u003c\/strong\u003e Dual-element, time-delay, non‑indicating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eLength: 2.00 in (approx. 50.8 mm)\u003c\/li\u003e\n\u003cli\u003eDiameter: 0.56 in (approx. 14.2 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e ~0.5 lb (approx. 0.23 kg)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCE Marked\u003c\/li\u003e\n\u003cli\u003eUL 248‑12 Listed\u003c\/li\u003e\n\u003cli\u003eCSA C22.2 No. 248.12 Certified\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese certifications confirm that the ECNR30 meets rigorous international and North American safety and performance standards — giving you confidence in its compliance and safe application in regulated environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere It Works Best\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Branch Circuits:\u003c\/strong\u003e Chauffeurs, compressors, conveyors — any motor circuit with startup surges benefits from a time-delay fuse.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransformers:\u003c\/strong\u003e Provides dependable protection from overloads and short circuits without nuisance trips during energizing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLighting and Heating Circuits:\u003c\/strong\u003e Offers reliable overcurrent protection for lighting banks, heaters, or resistive loads in commercial facilities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneral Electrical Systems:\u003c\/strong\u003e From distribution panels to auxiliary circuits, the ECNR30 protects a broad array of electrical applications with steady, dependable performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
