ABB TF65-47 Overload Relay

ABB TF65-47 Thermal Overload Relay is a three-pole protective device in the TF65 family that guards three-phase motors from overload by monitoring current and tripping when overload conditions are detected, helping prevent motor damage and unplanned downtime. It covers a continuous current range of 36 to 47 A and is specified with trip class 10, delivering precise, reproducible protection for motors in light- to medium-duty applications such as conveyors, pumps, and fans that run on 50/60 Hz power. Designed for AF40 to AF65 motor frames, the TF65-47 integrates a built-in auxiliary contact (1NC-1NO) that provides signaling to control circuitry, while its 690 VAC rating (3-phase) supports common industrial distributions. The unit is engineered for DIN-rail mounting, with compact dimensions roughly 101.4 mm high, 54.9 mm wide, and 106.9 mm deep, allowing installation in crowded panels and easy retrofits alongside ABB contactors and motor starters. Operating at 50/60 Hz, the TF65-47 is a standard choice when a robust, field-serviceable overload protection solution is required for reliable motor operation in automation and manufacturing environments.
