It offers 10 kA interrupting capacity at 480Y\/277 V AC and 96 V DC, with a rated ultimate short-circuit breaking capacity of 15 kA at 400 V AC, making it suitable for distribution feeders and motor-control circuits in DIN-rail mounted enclosures. As part of the SU200M family, this 3P device is compact and DIN-rail ready for modular electrical distribution systems, and it complies with IEC\/EN 60947-2, UL 489, and CSA 22.2 No. 5. With a rated current of 30 A, the SU203M-C30 is widely used in control panels, machinery feeders, and general distribution where predictable overload protection and reliable short-circuit performance are required. Physical dimensions are 69 mm long, 52.5 mm wide, and 111 mm high, and the unit has a total power loss around 10.5 W (3.5 W per pole) under rated conditions, reflecting its thermal-magnetic trip mechanism. In practice, choose this model when you need a robust, UL489-listed 30 A 3P breaker for high-demand circuits in DIN-rail panel boards. \u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656717795630,"sku":null,"price":171.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_dcc7062b-d3e7-4f2e-8900-0c645995a4e4.jpg?v=1769462902","url":"https:\/\/plgautomation.com\/products\/abb-su203m-c30-circuit-breaker","provider":"PLG Automation ","version":"1.0","type":"link"}
