It is designed to switch motor loads in control panels, with motor power ratings reaching 5.5 kW at 380-415 V AC and 4 kW at 480 V AC. The AC-3 rating of 12 A at 440 V is the key selection parameter for motor starting — this contactor will handle a 5.5 kW motor at 400 V class supplies. The AC-1 rating (resistive load) and AC-4 rating (plugging/inching) are also listed, giving flexibility for non-motor loads. The 200-208 V AC coil means it pulls in reliably on common 208 V control transformers found in North American panels. Heat dissipation is 1.3 W, so thermal buildup in a crowded DIN-rail enclosure is minimal. Flame retardance meets V1 per UL 94, plus NF F 16-101 and 16-102 requirements — relevant for rail or transit applications where fire safety is specified. The 3 NO pole composition and single NO auxiliary contact are typical for direct-on-line motor starters.","metaTitle":"TeSys K LC1K12103L7 Contactor, 3P, 12A AC-3, 200-208VAC Coil","metaDescription":"Obsolete TeSys K contactor LC1K12103L7, 3P, AC-3 <=440V 12A, 1 NO aux, 200-208VAC coil.
