At 3 amps, it’s mainly used in control circuits, instrumentation setups, and other low-current applications where even a small fault can cause bigger problems if it’s not caught early.\u003c\/p\u003e\n\u003cp\u003eWhat makes this fuse useful in real-world setups is how it behaves during normal operation. With its dual-element, time-delay design, it can handle short bursts of current—like what you get when equipment first powers up—without tripping right away. That helps avoid those frustrating nuisance blows that can shut a system down for no real reason. When a true overload or fault does happen, though, it reacts quickly to protect the circuit.\u003c\/p\u003e\n\u003cp\u003eIn day-to-day work, it’s the kind of fuse electricians don’t think twice about using because it fits standard Class RK5 fuse blocks and drops right into place. No special setup or modifications needed. The finger-safe design is another practical touch—it just makes handling a little safer and more comfortable when you’re working inside a crowded panel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3A Class RK5 dual-element fuse for low-current protection\u003c\/li\u003e\n\u003cli\u003e600V rating for industrial and commercial electrical systems\u003c\/li\u003e\n\u003cli\u003eTime-delay design helps ride through normal startup surges\u003c\/li\u003e\n\u003cli\u003e200kA interrupt rating for strong fault protection\u003c\/li\u003e\n\u003cli\u003eDual-element construction improves coordination in the system\u003c\/li\u003e\n\u003cli\u003eFinger-safe design for safer handling during install and maintenance\u003c\/li\u003e\n\u003cli\u003eFits standard RK5 fuse holders and blocks\u003c\/li\u003e\n\u003cli\u003eGood fit for control and instrumentation circuits\u003c\/li\u003e\n\u003cli\u003eHelps reduce nuisance blowing in real-world conditions\u003c\/li\u003e\n\u003cli\u003eReliable protection in compact electrical setups\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\u003eCatalog Number:\u003c\/strong\u003e ECSR3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass:\u003c\/strong\u003e RK5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating:\u003c\/strong\u003e 200 kAIC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Type:\u003c\/strong\u003e Dual-element\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e 10 sec at 500% overload\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Indicator:\u003c\/strong\u003e Non-indicating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Finger-safe construction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 5 in (L) x 0.81 in (W) x 0.81 in (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging Type:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ECSR3 Eaton Edison fuse is CE marked, showing it meets recognized safety standards for electrical protection components.
