The unit is specified for 800 A on the primary side with a 5 A secondary output, aligning with common 800 A\/5 A CT configurations used to feed meters and protective relays in electrical distribution systems. As a member of the Brown Boveri BBC lineage, the 401740-K5 suffix identifies a particular variant within the 401740 family, and the part is documented in supplier catalogs and ABB-era literature as a 401740-K5 current transformer. The model appears in distributor catalogs such as Piedmont Dielectrics and Radwell, confirming its status as an 800 A class CT, with related variants like 401740-K4 and 401740-K6 representing different primary\/secondary configurations. This current transformer provides a robust means to monitor high-current feeders by delivering a standardized 5 A secondary current to meters or protection relays. \u003c\/p\u003e\u003c\/div\u003e","brand":"BROWN","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677347807534,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_a5f4a9dd-fe26-4418-96af-5a5fc02af15f.jpg?v=1769561522","url":"https:\/\/plgautomation.com\/products\/brown-boveri-401740-k5-800-a-current-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
