It is designed to provide overcurrent and short-circuit protection in supplementary protection applications and is listed under UL 1077. Licensed electricians and panel builders install this device in load centers, control panels, and distribution boards where reliable branch-circuit or equipment protection is required. The B-curve trip characteristic makes it well suited for resistive and light inductive loads.\u003c\/p\u003e\u003cp\u003eThe ST202M-B25 is intended for supplementary protective applications in residential and light commercial electrical systems. It fits into DIN-rail-mounted enclosures and control panel assemblies where a compact, dual-pole breaker is needed. Its 25-amp rating and B-curve response are appropriate for circuits serving resistive heating elements, lighting loads, and similar equipment with low inrush current demands. UL 1077 listing confirms suitability for use in North American supplementary protection applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eB-curve trip characteristic for resistive and low-inrush load protection\u003c\/li\u003e\n\u003cli\u003e25-amp continuous current rating\u003c\/li\u003e\n\u003cli\u003e2-pole configuration for simultaneous disconnection of both conductors\u003c\/li\u003e\n\u003cli\u003e10 kA interrupting capacity for reliable short-circuit protection\u003c\/li\u003e\n\u003cli\u003eUL 1077 listed for supplementary overcurrent protection\u003c\/li\u003e\n\u003cli\u003eDIN-rail mount design for compact panel installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style supplementary circuit breaker for DIN-rail-mounted control panels and distribution enclosures requiring a 2-pole, 25-amp, B-curve MCB with UL 1077 listing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel or enclosure before installing or replacing the breaker. Verify that conductor sizing and terminal torque requirements match the panel assembly documentation. UL 1077 listed breakers are rated for supplementary protection and are not intended as branch-circuit protection replacements without engineering review.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 25 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Curve\u003c\/strong\u003e: B-curve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 10 kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL 1077\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ST202M-B25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383127671090,"sku":"ST202M-B25","price":97.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673114.png?v=1782588358","url":"https:\/\/voomisupply.com\/products\/abb-st202m-b25-miniature-circuit-breaker-2p-25a-b-curve","provider":"Voomi Supply","version":"1.0","type":"link"}
