Schneider Electric LC1D25 Non Reversing Contactor

Schneider Electric LC1D25 Non Reversing Contactor with LADN20 Auxiliary Block is a TeSys Deca control assembly that pairs a non-reversing main contactor with an integrated front-mounted auxiliary block (LADN20) to add two normally open contacts for signaling or interlock logic in control circuits. The LADN20 auxiliary block is designed for LC1D-series contactors and provides two NO contacts, rated for up to 690 V AC operation at 25...400 Hz, with instantaneous operation and a 1.5 ms non-overlap time between the energization of the NO paths and the corresponding logic signals. The front‑mounting design simplifies wiring, using screw-clamp terminals for secure connections, and keeps the auxiliary contacts aligned with the main contacts for compact panel layouts. This combination is intended for standard industrial AC load control where a built‑in signaling path is desirable, such as motor control circuits, interlocks, or PLC inputs, without needing separate auxiliary devices. As part of Schneider Electric’s TeSys Deca family, the LC1D25 non‑reversing model is a common, reliable choice for applications that require dependable main switching plus immediate auxiliary signaling in a single unit, with LADN20 serving as a two‑contact add‑on accessory for LC1D09 to LC1D150 devices.
