The utilisation categories cover AC-1 (resistive), AC-3 (squirrel-cage motor starting), and AC-4 (plugging/reversing). ## Motor power map and current ratings This contactor handles 5.5 kW at 380...415 V AC and at 440 V AC, 4 kW at 480 V AC and at 500...600 V AC and at 660...690 V AC, and 3 kW at 220...230 V AC — all at 50/60 Hz. The rated operational current [Ie] is 20 A, but the AC-3 motor switching rating is 12 A (at ≤440 V). The short-time withstand current [Icw] for the power circuit is 115 A for 1 s at 50 °C, stepping down to 55 A for 1 minute and 25 A for ≥15 minutes — important for coordination studies when sizing upstream protection. ## Physical integration and panel fit Heat dissipation is 3 W, so no special ventilation in a typical panel. Flame retardance meets UL 94 V1 and NF F 16-101/102 class 2, which matters for rail and transit applications where fire-smoke-toxicity requirements apply. ## Sourcing reality — obsolete part Obsolete per the manufacturer. Sourcing is through independent channels — we quote against an RFQ on a per-lot basis.","metaTitle":"Schneider LC7K12107M7 TeSys K Contactor, 3P, 12A AC-3, Obsol","metaDescription":"Schneider TeSys K LC7K12107M7 contactor, 3P, AC-3 <=440V 12A, 1 NO aux, 220-230V AC coil.
