Schneider Electric LC2D18B7 TeSys 3P Contactor

Schneider Electric LC2D18B7 TeSys Deca reversing contactor is a 3-pole, 3 NO (Form A) AC-3 power switch designed for forward/reverse motor control. It switches motor loads up to 440 V AC and 18 A, and is energized by a 24 V AC coil. The LC2D18B7 is part of the TeSys D family, featuring robust screw-clamp terminals for secure field wiring and a compact footprint suited to control panels. This reversing contactor is intended for AC-3 duty, typically used to start and reverse small- to mid-size AC motors in applications such as conveyors, fans, and pumps. The device provides reversing capability when used with an interlocking scheme and a companion contactor, allowing bidirectional motor operation with a single control input. With three normally-open main contacts, it offers straightforward, reliable switching for standard motor loads, and its 24 V coil aligns with common control circuits in industrial automation. Typical installations pair the LC2D18B7 with appropriate protective devices and wiring accessories to implement a safe reversing drive for light-to-medium industrial equipment.
