The Schneider Electric LP2K1210JD3 is a TeSys K reversing contactor — a compact 3-pole unit rated for 12 A in AC-3 duty at up to 440 V, with a 12 V DC coil and one normally-open auxiliary contact built in. The AC-3 rating of 12 A at ≤ 440 V means it handles the inrush and switching of a standard three-phase squirrel-cage induction motor up to roughly 5.5 kW at 400 V — the typical load for a small conveyor, pump, or fan. It also carries AC-1 (resistive) and AC-4 (plugging/reversing) utilisation categories, so it's rated for the full duty cycle of reversing applications, not just steady-state running.
The 12 V DC coil pulls in reliably at the nominal voltage. Verify the coil suppression matches your PLC output card's sink current; a free-wheeling diode across the coil is standard practice to protect the output transistor from the inductive kick.
Rated for ambient operation from -25 °C to 50 °C and storage from -50 °C to 80 °C, with no derating up to 2000 m altitude. The V1 flame-retardance rating per UL 94 means the housing material self-extinguishes — a standard requirement for panel-mounted control gear.
