The 1 NO auxiliary contact is built in. Motor power ratings span 3 kW at 220-230 VAC up to 5.5 kW at 380-415 VAC and 440 VAC, and 4 kW at 480 VAC and 500-690 VAC, all at 50/60 Hz. The 380-400 VAC coil is a direct line-voltage coil — no control transformer needed if the panel supply matches. Heat dissipation is 1.3 W, negligible for panel thermal budgeting. Flame retardance meets UL 94 V1 and NF F 16-101/102 requirements, which is standard for rail and industrial panel equipment. The 3 NO power poles and single NO auxiliary fit within that envelope, leaving room for adjacent devices in a crowded panel.","metaTitle":"TeSys K LC1K12103Q7 Contactor, 3P, 12 A AC-3, 380-400 VAC Co","metaDescription":"Obsolete TeSys K LC1K12103Q7 contactor. 3P, AC-3 12 A at ≤440 V, 1 NO aux, 380-400 VAC coil.
