Square D LC1K1210F7 Three-Phase AC Contactor

LC1K1210F7 is a TeSys K three‑pole AC contactor from Schneider Electric, engineered for reliable, in‑panel motor control in demanding industrial environments, with robust contacts and standardized mounting that suits modular control cabinets. It provides three power contacts in a 3P configuration that are normally open (3PST‑NO) and rated for up to 12 A on AC‑3 duty, with a maximum switched voltage of 440 V AC, enabling dependable motor start/stop for three‑phase loads and delivering up to approximately 5.5 kW of motor power at 400 V. The device includes one normally open auxiliary contact (1 NO) for signaling, interlocking, or control circuit feedback, and it is energized by a 110 V AC coil, aligning with common control voltages used in European and many global automation installations. Mounting flexibility is provided through chassis or DIN rail options, consistent with the TeSys K family, supporting compact panels and modular multi‑contactor assemblies.
