Square D LC1K0910G7 Three-Phase Contactor

Schneider Electric TeSys K LC1K0910G7 is a three-pole AC-3 contactor with a 120 V AC coil, designed to control three-phase motors and other AC loads. The device switches three main contacts and includes one auxiliary contact; it is rated for AC-3 duty up to 440 V and 9 A, with a motor-load rating around 4 kW at the appropriate voltage. The coil operates from 120 VAC, enabling reliable energization from standard control circuits, while the compact TeSys K form factor suits panel mounting in industrial control cabinets. This LC1K0910G7 variant provides one additional auxiliary (NO) contact for signaling or interlocking in control circuits, expanding wiring options for start/stop interlocks and logic circuits. Typical applications include conveyors, fans, pumps, and machine tools where a compact, reliable contactor is required to switch the motor load with a 120 V control signal. The part is part of Schneider Electric’s TeSys K family, designed for ease of integration with common PLC control schemes and compatible with standard mounting rails and accessories in industrial environments.
