The LC2K09103K7 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit rated AC-3 at 9 A up to 440 V, with a 100 V AC coil. It comes preassembled with the reversing power busbar, so you're not hunting for the mechanical interlock and bus kit separately; that's one less line item to track in the storeroom. Rated for utilisation categories AC-1, AC-3, and AC-4, it handles resistive loads and motor control. That's a small motor, maybe 3–4 kW depending on the duty cycle. IP20 finger-safe protection (VDE 0106) means it's meant for an enclosed panel, not a washdown zone. Operating range is -25 to 50 °C ambient, which covers most control rooms and machine cabinets without derating.
AC-3 means making and breaking stalled-rotor currents during starting — about 6× the full-load current for a brief interval. Flame retardance meets UL 94 V1 and NF F 16-101/102, which is typical for rail and industrial control gear. The mechanical shock ratings — 10–15 Gn depending on axis and contactor state — tell you it holds in on a vibrating conveyor or a punch press without dropping out.
