The Schneider Electric LP2K1210MUD3 is a TeSys K reversing contactor — a 3-pole unit rated for AC-3 motor duty at 12 A up to 440 V, with a 240 V DC coil and one normally open auxiliary contact. It comes preassembled with the reversing power busbar, so you don't have to build the mechanical interlock and bus wiring yourself; it's ready to drop into a panel and wire the motor leads and coil control.
The preassembled reversing busbar saves space and wiring time compared to building the interlock with two separate contactors and a mechanical link. The 3 NO power poles handle the motor phases; the single NO auxiliary contact can be used for a status feedback to the PLC or to seal in the coil circuit. The coil is 240 V DC, so the control circuit needs a DC supply — not uncommon in modern panels with 24 V DC control, but 240 V DC is less common. Verify your control transformer and rectifier setup before wiring.
