Its headline motor rating is 4 kW at 480 V AC, 50/60 Hz — that's the figure to match against your motor nameplate for the line voltage you're running. The AC-3 utilisation category means it's designed for starting and stopping squirrel-cage induction motors under load, not just resistive switching. At ≤440 V AC-3, it's rated 12 A, so the 4 kW at 480 V lines up with typical IEC motor sizing. The coil is 24 V AC, which is common for panel control transformers, but confirm your control voltage is AC — a DC coil won't hold in on this one. Rated operational current is 20 A for AC-1 duty. Short-time withstand current is 115 A for 1 second on the power circuit. Heat dissipation is 3 W. TeSys K contactors are the compact workhorses for motor control in industrial panels — conveyors, pumps, fans, compressors up to about 5.5 kW. The 45 mm width and 58 mm height make them a standard fit for 35 mm DIN rail enclosures. The flame retardance rating V1 per UL 94 means the housing material self-extinguishes, which matters for panel certification to UL 508A or IEC 60947.","metaTitle":"Schneider Electric TeSys K LC7K12105B7 Contactor, 3P, 12 A A","metaDescription":"Schneider Electric TeSys K contactor LC7K12105B7, 3P, 12 A AC-3 at ≤440 V, 4 kW motor at 480 V, 24 VAC coil, 1 NO aux.
