Schneider Electric LC1D09F7C is a 3‑pole electromechanical AC contactor from the TeSys D series designed for motor control and general switching applications in industrial and commercial electrical systems. It features three main power contacts and integrated auxiliary contacts for control and signalling functions. The contactor is suitable for switching alternating current (AC) loads such as small three‑phase motors, lighting, heating, and other resistive or inductive circuits. It is engineered for reliable performance, long electrical life, and robust mechanical endurance, and supports panel or DIN‑rail mounting in control panels and distribution systems.
