The Schneider LC1K12013E7 is a TeSys K miniature contactor — three poles, normally open main contacts, and one normally closed auxiliary contact built in. It is rated 12 A in AC-3 duty (switching motor loads) at supply voltages up to 440 V, with a 48 V AC 50/60 Hz coil. The utilisation categories cover AC-1 (resistive), AC-3 (squirrel-cage motor starting/running), and AC-4 (plugging/inching), so it handles both steady-state and high-stress switching cycles. 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 or 500–690 V — a wide voltage range that suits export panels or multi-voltage installations. Heat dissipation is 1.3 W, modest enough for dense DIN-rail layouts without forced cooling.
Short-time withstand and auxiliary contact ratings
The power circuit can withstand 115 A for 1 second (Icw), tapering to 55 A for 1 minute and 25 A for 15 minutes or longer — useful for coordinating with upstream motor-protective breakers during fault clearing. The signalling circuit (auxiliary contact) handles 110 A for 100 ms and 80 A for 1 second, adequate for pilot-duty switching of PLC inputs or relay coils.
