It offers a setting range of 22–28 A per pole and carries a Class 10 thermal rating, making it suitable for standard motor protection tasks in industrial controls. Key electrical characteristics include a resistance per pole of 3.937 mΩ and a per‑pole power loss ranging from 1.9 W to 3.1 W depending on the setting. For system coordination, the TF65‑28 is specified to work with short‑circuit protection device coordination type 2 using 80 A gG fuses. This model is part of ABB’s TF65 family of thermal overload relays, specifically identified as TF65-28, and is intended to protect motors in line with AF40-65 contactors by limiting current before damage occurs while enabling precise adjustment within its 22–28 A range. \u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656708882734,"sku":null,"price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1bb78665-74ed-4776-8638-43f5e70c48ce.jpg?v=1769462835","url":"https:\/\/plgautomation.com\/products\/abb-tf65-28-thermal-overload-relay-tf65-28-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
