It features a K-type tripping characteristic, making it suited for loads with moderate inrush currents such as transformers and mixed resistive-inductive loads. The breaker carries a UL489 listing with a 10 kA interrupting rating under UL standards and a 15 kA interrupting rating under IEC standards, giving installers flexibility across North American and international panel configurations. Licensed electricians are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThe su203m-k60 is applied in 3-phase electrical distribution panels in commercial buildings, light industrial facilities, and equipment control enclosures where branch-circuit protection is required. The K-curve characteristic distinguishes it from standard B- or C-curve breakers, targeting circuits where brief high-magnitude inrush currents must be tolerated without nuisance tripping. It fits within the ABB SU200M series breaker family and is suitable for both UL and IEC-governed installations depending on the panel listing requirements of the project.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK-type tripping curve for inrush-tolerant overcurrent protection\u003c\/li\u003e\n  \u003cli\u003e60 amp continuous current rating\u003c\/li\u003e\n  \u003cli\u003e3-pole configuration for 3-phase branch-circuit protection\u003c\/li\u003e\n  \u003cli\u003e10 kA interrupting capacity per UL489\u003c\/li\u003e\n  \u003cli\u003e15 kA interrupting capacity per IEC standards\u003c\/li\u003e\n  \u003cli\u003e400 volt AC rated for international and dual-standard panel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specified replacement or new-installation breaker within the ABB SU200M series miniature circuit breaker platform, compatible with panel assemblies requiring UL489-listed 3-pole branch-circuit protection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize the panelboard completely before handling or installing the breaker. Verify that the panel busbar rating, wire gauge, and terminal torque specifications conform to the panel manufacturer's documentation and NEC Article 240 requirements. Do not install in a panel with a busbar voltage or fault-current rating that exceeds the breaker's listed ratings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 60 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 400 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTripping Curve\u003c\/strong\u003e: K-type\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (UL489)\u003c\/strong\u003e: 10 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (IEC)\u003c\/strong\u003e: 15 kA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL489\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct ID\u003c\/strong\u003e: 2CDS273337R0587\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: su203m-k60\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51620581114162,"sku":"SU203M-K60","price":188.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7517d51aa789d4acf63f2d1ed9263695.jpg?v=1787344175","url":"https:\/\/voomisupply.com\/products\/abb-su203m-k60-miniature-circuit-breaker-60a-3p-k-curve","provider":"Voomi Supply","version":"1.0","type":"link"}
