The Schneider Electric LC2K12103K7 is a TeSys K reversing contactor, 3-pole, rated for AC-3 duty at 12 A up to 440 V, with a 100 V AC coil. It ships preassembled with the reversing power busbar, so you don't need to wire the mechanical interlock or bus links separately — it's one unit, ready to bolt into the panel for forward/reverse motor control on conveyors, pumps, or fans. Rated for motor-switching loads (AC-3) and resistive loads (AC-1), it also carries an AC-4 utilisation category for inching or plugging duty. The 12 A AC-3 rating at 440 V means it handles a typical 5.5 kW motor on a 400 V line — match it to the motor FLA, not the contactor's thermal rating. The 100 V AC coil is a common control voltage in older European panels; verify your control transformer taps before wiring.
Lifecycle and sourcing reality — obsolete, sourced to order
If you need a form-fit-function replacement, the closest active TeSys K reversing contactor with a 100 V AC coil in the same 12 A AC-3 class is the LC2K1210B7 (24 V DC coil) or LC2K1210M7 (220 V AC coil) — but coil voltage differs, so a control-circuit redesign or a separate control transformer may be required. No pin-compatible drop-in exists with the same coil voltage.
Integration and mounting — panel fit
IP20 finger-safe terminals (per VDE 0106) mean it can sit in an open panel without extra shrouding.
