The LC7K1201M7 is a 3-pole contactor from the TeSys K range, rated for AC-3 and AC-3e duty at 12 A up to 440 V. The 12 A rating at 440 V is the current it can make and break in that category, so for a motor drawing, say, 9 A full-load current, this contactor has headroom. The coil is 220-230 V AC, and the control circuit operates reliably between 0.85 and 1.1 times Uc, with dropout below 0.1 Uc at temperatures under 50 °C. Electrical durability is stated per utilisation category: 1.3 million cycles at 12 A in AC-3 and AC-3e, 0.3 million cycles at 20 A in AC-1 (resistive), and 20,000 cycles at 72 A in AC-4 (plugging/inching). These figures give a clear picture of the contactor's expected life in different applications — the AC-4 figure is notably lower, as expected for the severe switching duty of reversing or inching. The B10d value of 1,369,863 cycles at nominal load (per EN/ISO 13849-1) supports use in safety-related control circuits.
The contactor mounts on a plate or DIN rail, with a footprint of 45 mm wide, 58 mm high, and 57 mm deep. Screw clamp terminals accept 1.5 to 4 mm² solid or flexible cable (one or two conductors), with a tightening torque of 0.8 to 1.3 N·m. The 3 W heat dissipation should be factored into the enclosure's thermal budget, especially in a densely populated cabinet.
