The Schneider Electric LC1K1210B7TQ is a 3-pole contactor from the TeSys K series, rated 12 A in AC-3 duty at 440 V — that's the motor-switching rating, so it handles a 3-phase induction motor up to roughly 5.5 kW at 400 V. The 24 V AC coil pulls in without a built-in bidirectional peak limiting diode, so if you're driving it from a PLC output, plan external suppression on the coil circuit to protect the solid-state output.
Rated operational current and utilisation categories
The utilisation categories cover AC-1 (resistive loads), AC-3 (squirrel-cage motors — starting and stopping under load), and AC-4 (plugging and inching). AC-1 rating is higher at 20 A, but that's for resistive loads like heaters.
