Schneider Electric LC1D12BDC 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, heating and other resistive or inductive circuits. The contactor is engineered for reliable performance, robust mechanical durability, and high electrical endurance. It supports standard control coil voltages and flexible mounting in control panels via DIN‑rail or panel installation, making it ideal for use in motor starters and control panel integration.
