It is DIN-rail mountable and built with finger-safe, multi-function terminals for straightforward panel installations in commercial and industrial environments. The device offers a short-circuit current rating (Icu) up to 6 kA and is rated for voltages up to 277 VAC (phase-to-neutral) \/ 480 VAC (phase-to-phase), making it compatible with common 480Y\/277 power systems. Construction features include robust internal metallic components and flame-retardant, halogen-free materials (V0 internal components), aligning with safety and environmental considerations. The S203-K3 carries UL 1077 and CSA 22.2 marks for supplementary protection, and its exact ABB part number is 2CDS253001R0317, confirming its place in ABB’s compact protection lineup for three-phase circuits. This model is well suited for distribution boards and control panels where compact, reliable protection of three-phase loads is required without external fusing. \u003c\/p\u003e\u003c\/div\u003e","brand":"ASEA","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660256936238,"sku":null,"price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9e781299-6613-4975-8d1c-8de426b4bafc.jpg?v=1769535231","url":"https:\/\/plgautomation.com\/products\/abb-s203-k3-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
