The Schneider Electric LR9D08KITD09G7 is a direct-on-line motor starter from the TeSys range, combining a contactor and thermal overload relay in one unit for three-phase motor control and protection. It covers motor power from 0 to 6 kW across supply voltages from 100-120 V to 525-690 V three-phase, with a thermal protection adjustment range of 0.4 to 2 A. The thermal overload class is adjustable from Class 5 to Class 30, letting you match the trip curve to the motor's starting characteristics — slow for high-inertia loads like fans, fast for pumps.
The 0.4-2 A adjustment range is the actual full-load current window you set on the dial. If your motor's nameplate FLA falls outside this band, this starter won't protect it — you'd step up to the next TeSys frame. Rated for utilisation categories AC-1 (resistive), AC-3 (squirrel-cage motor starting/running), and AC-4 (plugging/inching), so it handles both standard motor starts and reversing duty.
Mounts directly under a contactor on the plate, or on a rail with specific accessories — typical for a motor control centre or a standalone panel feeding a conveyor, pump, or compressor. Dimensions are 3.1 in deep, 1.8 in wide, 2.9 in tall — fits a standard 45 mm wide DIN footprint. Power circuit terminals accept up to 16 mm² solid or flexible cable; control circuit terminals take 2.5 mm². Tighten power terminals to 3.1 N·m, control to 0.8 N·m.
Compliance documentation is solid: UL 60947-4-1, IEC 60947-4-1, CSA C22.2, and GB 14048.4. Flame retardance is V1 per UL 94; glow-wire tested to 850 °C per IEC 60695-2-1.
