The Schneider Electric LC2K1210N7 is a TeSys K reversing contactor, 3-pole, rated AC-3 at 12 A up to 440 V, with a 400-415 V AC coil and one normally open auxiliary contact. Rated for utilisation categories AC-1, AC-3, and AC-4, it handles resistive loads, standard motor starting, and plugging or inching duty respectively. The AC-3 rating is the one that governs motor switching — 12 A at 440 V covers a 5.5 kW motor at 400 V, typical for small conveyors, pumps, or fans where direction reversal is needed.
There is no direct factory replacement announced; any substitute would require a form-fit-function evaluation against the panel's existing footprint and wiring.
The contactor measures 90 mm wide by 58 mm high by 57 mm deep. No derating is needed up to 2000 m altitude.
