The Schneider Electric LP2K1201MD3 is a TeSys K reversing contactor, 3-pole, rated for AC-3 duty at 12 A up to 440 V — that's the motor-switching current, so it handles a 3-phase induction motor in that range. The coil is 220 V DC, which means you need a DC supply or a rectified AC source for the magnet. It comes preassembled with the reversing power busbar, saving panel-build time for forward-reverse motor control. The utilisation categories cover AC-1 (resistive loads), AC-3 (squirrel-cage motors: starting, stopping, switching under load), and AC-4 (plugging, inching, reversing under full load). For reversing duty, AC-4 is the heavy case — the contactor is rated for that, so it can handle the high inrush and breaking current of a motor reversal cycle.
This is a panel-mount reversing contactor, sized for DIN-rail or screw-mount integration. IP20 finger-safe protection means it's suitable for enclosed panels where personnel don't contact live parts. The preassembled reversing busbar eliminates the need to wire a mechanical interlock and power loop between two separate contactors — it's a single unit that reverses phase rotation on command. The 1 NC auxiliary contact provides a feedback or interlock signal.
