The part number 0126A07282-3 uniquely identifies this ABB high-ratio CT within ABB’s catalog, ensuring compatibility with ABB measurement and protection architectures that expect a 5 A secondary. This current transformer is used to scale down large primary currents to levels suitable for meters, relays, and data acquisition systems, allowing safe, continuous monitoring of load, fault detection, and system performance without exposing measurement equipment to the full primary current. Typical applications include feeders, switchgear, and panel boards where high-current measurement is required and a standard 5 A secondary is preferred for compatibility with common protection relays and metering instruments. The 250:5 ratio provides a 50:1 reduction, meaning a 250 A primary yields a 5 A secondary, which is a common standard in many electrical distribution and protective schemes, simplifying integration with existing 5 A instrumentation and CT input modules.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656944517422,"sku":null,"price":303.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_193078de-94a5-435d-9062-b5d32179a8bf.jpg?v=1769464529","url":"https:\/\/plgautomation.com\/products\/abb-0126a07282-3-high-ratio-current-transformer","provider":"PLG Automation ","version":"1.0","type":"link"}
