It is rated for 63 A with a D-trip characteristic, offering reliable overload and short-circuit protection for three live conductors fed from a common supply. Electrical ratings specify 240 V AC (125 V DC) nominal operating voltage, with an interrupting capacity of 10 kA at 240 VAC, 5 kA at 480Y\/277 VAC, and 10 kA at 125 V DC, making it suitable for a range of industrial electrical networks. The device uses screw terminals for secure wiring and is UL 1077 listed, reflecting compliance for supplementary protection in electrical panels; ABB catalogs list ST203M-D63 under the ST200M series with ordering code 2CDS273334R0631. Typical applications include protection of three-phase motors, machine control circuits, and distribution panels in manufacturing and process environments where a compact 63 A, D-characteristic breaker is desired.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656721400110,"sku":null,"price":196.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3db8bbd1-9c8d-4a2b-9144-0efee142f2c3.jpg?v=1769462937","url":"https:\/\/plgautomation.com\/products\/abb-st203m-d63-programmable-safety-relay-module","provider":"PLG Automation ","version":"1.0","type":"link"}
