The most common and official software for this purpose is (also known as Curve Tool ), though other ABB platforms like Relion® Protection and Control IED Manager PCM600 or Softstarter configuration tools also include curve functionality.
CurveTool covers most electromechanical and static relay curves. Modern Relion relays are better served with PCM600.
Always download from official ABB portals. Avoid “free download” sites — they often distribute outdated or infected files.
If you work with ABB protection relays, soft starters, or circuit breakers, you’ve likely searched for “ABB curves software download.” The term usually refers to tools that allow you to view, edit, or test time-current curves (TCC) , torque-speed curves , or thermal curves for ABB devices.
