Schneider Electric LC1DT40 Reversing Contactor

Schneider Electric LC1DT40 Tesys D reversing contactor is a four‑pole motor‑control device designed to reverse a three‑phase load in forward/reverse applications. With 40 A rated current on AC‑1 duty, it switches the main power lines and is commonly paired with a companion LC1D reversing partner and interlock accessories to deliver safe bidirectional control in control panels. The LC1DT40 family is offered with a range of coil voltages to suit typical control voltages, including 32 V AC (LC1DT40C7), 120 V AC (LC1DT40G7), 220 V AC (LC1DT40M7), and 240 V AC (LC1DT40U7), reflecting TeSys D’s broad compatibility for 50/60 Hz systems. In standard configurations, the power circuit is rated for AC‑1 up to about 440 V, with higher‑voltage variants available in the TeSys D lineup depending on coil/model; Schneider’s literature catalogs LC1DT40 among reversing contactors and notes its use with overload relays and interlocks to form complete forward/reverse control schemes. Typical applications include conveyors, pumps, and fans, or machine tools where reversing a three‑phase motor is required; to ensure safe interlocking of the two opposing contactors, accessories such as LAD9R1V interlocks are used in conjunction with TeSys D devices. As part of Schneider Electric’s TeSys D ecosystem, the LC1DT40 provides a reliable replacement option for existing LC1DT40 installations within properly rated panels.
