The LC1D50ABD is a three-pole electromechanical contactor from Schneider Electric's widely-used TeSys D series. Designed for reliable power switching, it is primarily used for controlling three-phase motors, but also suitable for resistive and inductive loads such as heaters, lighting, and capacitor banks.
