The Schneider Electric LP1K09103JD is a TeSys K series 3-pole contactor rated for 9 A in AC-3 duty at up to 440 V, with a 12 V DC coil. That AC-3 rating means it handles the high inrush of starting squirrel-cage motors — the 9 A figure is the continuous motor current it can switch, not the resistive load curve. Three normally-open main poles and one normally-open auxiliary contact (1 NO) are built in. The utilisation category list (AC-1, AC-3, AC-4) tells you it can also handle resistive loads (AC-1) and plugging/reversing duty (AC-4), but the 9 A AC-3 figure is the one that governs motor-switching applications. Flame retardance is rated V1 per UL 94, which means the housing self-extinguishes within a vertical burn test — relevant for panel builders who need to meet NF F 16-101 or 16-102 railway fire-smoke-toxicity requirements.
The 3P + 1 NO auxiliary arrangement is typical for a small motor starter or a feed interlock; the auxiliary contact can be wired into the PLC input for feedback without needing a separate block. The 12 V DC coil is common in 24 V DC control buses with a step-down regulator, or in battery-backed safety circuits where a lower coil voltage reduces arc energy on dropout.
