ABB T25-DM is a three-pole solid-state overload relay used to protect motors in three‑phase circuits by monitoring load current and tripping when an overload condition is detected. This model belongs to ABB's T25 family (originally ASEA BROWN BOVERI) and is rated for up to 600 V, with variants such as the T25-DM-18-23A specifying an 18–23 A load current. The T25-DM series has historically served motor-protection roles in industrial automation, and ABB lists this specific model as discontinued by the manufacturer, with remaining stock available through distributors.
