The LP2K1210CD3 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit rated AC-3 at 12 A up to 440 V, with a 36 V DC coil and one normally-open auxiliary contact. It ships preassembled with the reversing power busbar, so you don't need to source and fit the interlock kit separately; it's ready to drop into a panel and wire up for motor reversing duty.
The AC-3 rating of 12 A at 440 V is the motor-switching current — that's the number that decides fit for a reversing starter on a 3-phase induction motor up to about 5.5 kW at 400 V. The AC-1 rating (resistive load) will be higher, but for motor control, AC-3 is the one that governs contactor life. The 36 V DC coil means it pulls in cleanly on a standard control transformer or battery-backed DC supply; hold-in power is low enough that a small PLC relay can drive it directly.
Where you'll find it
This is a panel-mount reversing contactor for motor control centres, conveyor drives, pump reversing, and any application where you need to swap motor rotation without a separate mechanical interlock. The IP20 finger-safe enclosure (per VDE 0106) means it's suitable for enclosed panels where personnel might reach inside — no extra shrouding required for basic touch protection.
