It handles motor loads up to 4 kW at 480 V AC, 5.5 kW at 380-415 V, and 3 kW at 220-230 V — so it covers common three-phase motor sizes across North American and European voltage standards. Built-in bidirectional peak limiting diode suppression on the coil means you don't need an external snubber for inductive kickback — one less part to panel-mount and one less wiring step. At 1.3 W heat dissipation, this contactor adds negligible thermal load to a cabinet — you can pack it tight without worrying about derating adjacent components. Rated for AC-1 (resistive), AC-3 (squirrel-cage motors), and AC-4 (plugging/inching) duty — the AC-3 figure governs most conveyor, pump, and fan starts; the AC-4 rating matters if the application reverses or jogs the load frequently. Flame retardance to UL 94 V1 and NF F 16-101/-102 means the housing self-extinguishes — relevant for rail, marine, and any panel subject to fire-safety inspection.","metaTitle":"Schneider TeSys K LC1K12105M72 Contactor, 3P, AC-3 12A, 220-","metaDescription":"Active TeSys K contactor, 3P, AC-3 ≤440V 12A, 1 NO aux, 220-230VAC coil.
