This is the control-class contactor for switching motor loads, resistive loads, and general on/off control in panels and machinery. The 12 A AC-3 rating means it handles typical small motor starting currents (inductive load) without welding the contacts, while the AC-1 rating covers resistive loads like heaters. It's built to EN/IEC 60947-4-1 and carries UL, CSA, and JIS approvals, so it slots into global designs without requalification. The headline 12 A AC-3 rating governs motor switching — that's the current you size against your motor's full-load amps. The electrical durability at that rating is 1.3 million cycles, which is solid for a compact contactor in a small conveyor or pump panel. Mechanical durability is 10 million cycles, so the mechanism outlasts the electrical life under normal use. The coil pulls 30 VA inrush and holds at 4.5 VA, so a 24 V 50 Hz control transformer needs to handle that inrush without voltage sag. The IP20 finger-safe terminals (per VDE 0106) mean it's safe for open-panel mounting but not for washdown environments. Dimensions are 45 mm wide, 58 mm high, 57 mm deep — it's a compact footprint that fits standard 45 mm-wide DIN-rail spacing, so three of these sit side by side in a 135 mm-wide slot. Screw clamp terminals accept 1.5 to 4 mm² solid or flexible wire, with a tightening torque of 0.8 to 1.3 Nm. The single 1 NO auxiliary contact is built in; if you need more, you add a side-mount auxiliary block from the TeSys K range.","metaTitle":"Schneider LC1K1210B5 TeSys K Contactor, 12A AC-3, 24V 50Hz","metaDescription":"Schneider Electric TeSys K contactor LC1K1210B5. 3-pole, 12A AC-3/AC-3e, 1 NO aux, 24V 50Hz coil.
