Schneider Electric LC1D18BD Three Phase Contactor

Schneider Electric LC1D18BD TeSys D three-pole AC-3 contactor, with three normally open contacts and a 24 V DC coil, is designed for reliable on/off control of 3‑phase motors and other AC loads in industrial control panels. It is rated for AC‑3 operation up to 440 V and 18 A, making it suitable for starting and stopping motors such as conveyors, pumps, fans, and machine tools. The LC1D18BD family supports motor power ranges around 7.5 kW at 400 V (about 10 HP at 480 V) and carries a short-circuit current rating (SCCR) up to 100 kA, enabling safe operation when coordinated with compatible overload protection. As part of Schneider Electric’s TeSys D line, this contactor offers a compact, widely used solution for mid‑range motor control in commercial and industrial applications, where a dedicated control coil is energized by 24 V DC from a common control circuit. Applications include general motor starting in manufacturing lines, material-handling equipment, blowers, and compressors, where reliable switching and coordination with overload relays are required.
