That AC-3 rating means it's sized for starting and stopping squirrel-cage motors under load — the contactor's rated operational current (Ie) of 12 A in AC-3 is the figure that governs motor switching, not the higher AC-1 resistive rating. Motor power capability spans 3 kW at 220–230 V up to 5.5 kW at 380–440 V, and 4 kW at 480 V through 690 V — covering common three-phase supply voltages across global sites. The coil uses a built-in bidirectional peak limiting diode suppressor, which simplifies panel wiring by eliminating the need for an external flyback diode or RC snubber across the coil terminals. At 45 mm wide, 58 mm tall, and 57 mm deep, this contactor fits standard DIN-rail or panel-mount layouts common in control cabinets. The compact footprint leaves room for adjacent overload relays or auxiliary contact blocks in a motor starter stack. Flame retardance rated V1 per UL 94, and meets Requirement 2 per NF F 16-101 and NF F 16-102 — relevant for rail and transport applications where fire-smoke-toxicity standards apply.","metaTitle":"Schneider Electric LC1K12107F72 TeSys K Contactor, 12 A AC-3","metaDescription":"TeSys K contactor, 3P, AC-3 ≤440 V 12 A, 1 NO aux, 110 V AC coil.
