It uses a thermal‑magnetic trip mechanism with a K‑curve characteristic to provide overload protection and rapid short‑circuit action, helping to prevent damage in motor drives, control panels, and distribution blocks. Listed for North American use as a supplementary protector under UL 1077, this model sits in ABB’s ST200\/M family and is suitable for panel and enclosure installations in industrial environments. The ST203M-K60NA variant represents the North American market version, offering a 60 A nominal rating with a compact footprint appropriate for space‑constrained switchgear and control cabinets. Verified specifications include 60 A, 3 poles, operation at 480Y\/277 VAC, and a K‑characteristic trip profile, making it a direct choice for protecting branch circuits feeding motors, contactors, and other 3‑phase equipment where reliable, code‑compliant protection is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"ASEA","offers":[{"title":"New","offer_id":51660255920430,"sku":null,"price":4060.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3fd707f0-57b4-4f51-a458-1f8fa2774550.jpg?v=1769535220","url":"https:\/\/plgautomation.com\/products\/asea-brown-boveri-st203m-k60-molded-case-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
