The Schneider Electric LP2K1210ED is a TeSys K reversing contactor — a 3-pole, 3-NO power pole device preassembled with the reversing power busbar, so it arrives ready to wire into a motor-reversing circuit without building the interlock yourself. Rated for AC-3 duty up to 12 A at ≤440 V, it handles the forward/reverse switching of a three-phase induction motor in that current class. The 48 V DC coil holds the unit on the grid provided the control supply stays within the operating temperature range of -25 to 50 °C.
The AC-3 utilisation category at 12 A is the motor-switching rating — that is the current the contactor can make and break across a starting induction motor load. AC-4 covers inching and plugging duty, and AC-1 covers resistive loads; the part is listed for all three, so it is not limited to one load type. The 48 V DC coil is a specific control voltage — not a common 24 V or 110 V, so verify the control transformer or PLC output matches before committing the BOM line. IP20 means finger-safe terminals but no protection against moisture ingress; this contactor belongs in a sealed enclosure, not exposed to washdown or outdoor conditions.
The contactor measures 90 mm wide by 58 mm high by 57 mm deep — a compact footprint for a reversing assembly, since the busbar is pre-fitted. It operates without derating up to 2000 m altitude. Vibration tolerance is 4 Gn closed, 2 Gn open across 5–300 Hz; shock resistance is 15 Gn closed on the Z axis for 11 ms. These numbers matter if the contactor lives on a machine frame or a moving gantry — the closed-contact ratings govern during normal running, the open-contact ratings govern during transit or shutdown.
