The Schneider Electric LP2K1201JD3 is a TeSys K reversing contactor — a 3-pole unit rated AC-3 ≤440 V at 12 A, with a 12 V DC coil and one NC auxiliary contact. It arrives preassembled with the reversing power busbar, so the mechanical interlock and bus connections are already in place. That saves panel-build time on motor-reversing circuits for conveyors, hoists, or any load that needs direction change.
The LP2K1201JD3 is listed as Obsolete.
AC-1 (resistive) and AC-4 (inching/plugging) utilisation categories are also listed, so the contactor is rated for those duty cycles too. The 12 V DC coil draws from a control supply common in low-voltage DC panels; verify your control transformer or power supply can deliver the inrush without droop. IP20 protection per VDE 0106.
Mechanical robustness and panel fit
The contactor is rated for 15 Gn shock on the Z axis when closed, and 10 Gn when open, per IEC 60068-2-27. Vibration resistance is 4 Gn closed, 2 Gn open across 5–300 Hz. That is enough for most industrial machinery but not for extreme off-road or marine engine mounts without additional damping.
