Schneider Electric LC2DD40AU7 Reversing Contactor

Schneider Electric LC2D40AU7 TeSys Deca reversing contactor is a three-pole switching device with three normally open contacts (3 NO) used for forward/reverse control of three‑phase motors. It is rated for AC-3 duty up to 440 V and 40 A, and it uses a 240 V AC coil (50/60 Hz). This model belongs to the TeSys Deca family and is designed for motor direction reversal in industrial control panels and machinery where compact, reliable switching is required. The 3-pole, 3 NO configuration and 240 V coil support straightforward integration into standard control circuits and wiring schemes for moderate-power motor applications, making it suitable as a replacement for aging reversing contactors or as part of a new reversing control circuit.
