Overview

The ABB TF65-67 thermal overload relay (SKU: TF65-67) is a cost-effective, electromechanical protection device engineered for reliable main circuit safeguarding of electric motors. Designed by ABB Electrification, this relay provides critical protection against overloads and phase failures, ensuring operational continuity and preventing costly equipment damage. With a Trip Class 10 rating, it delivers fast and precise tripping characteristics essential for motor safety in industrial applications. Key features include advanced temperature compensation for consistent performance across an ambient temperature range of -40°C to +70°C (valid for units produced from week 11, 2016; otherwise -25°C to +60°C). The device is equipped with a normally closed (NC) trip contact for immediate shutdown signaling and a normally open (NO) signal contact for remote monitoring. Users can select between automatic or manual reset functions, with a trip-free mechanism preventing resetting during a fault. A clear trip indication enables quick diagnostics. The TF65-67 is designed for direct mounting onto ABB block contactors (AF40 to AF65 series) or via a single mounting kit for 35 mm DIN rail installation. Electrical connection capabilities are extensive, supporting rigid, flexible, and stranded conductors for both main and auxiliary circuits. Main circuit terminals accommodate rigid conductors from 2.5 to 35 mm² or flexible conductors with ferrules from 2.5 to 35 mm², while auxiliary circuits support conductors from 0.75 to 4 mm². UL/CSA stranded and flexible conductors are supported up to AWG 2 (main) and AWG 12 (auxiliary). Additional features include phase loss sensitivity per IEC/EN 60947-4-1, ATEX certification (valid for products produced from week 26, 2015), and a maximum operating altitude of 2000 meters. The device is suitable for three- and single-phase applications, with a TEST and STOP function for operational flexibility. With a weight of 0.382 kg, the TF65-67 is a robust solution for motor protection in industrial environments.
