Schneider Electric LC1D18BDC is a compact 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 normally‑open power contacts and integrated auxiliary contacts, suitable for switching small three‑phase loads such as motors, lighting, and other resistive or inductive circuits. The contactor is engineered for reliable performance, robust mechanical durability, and high electrical endurance. It supports standard industrial control coil voltages and flexible panel or DIN‑rail mounting, making it ideal for motor starters and control panel integration.
