What this TeSys LG enclosed starter is
The Schneider LG7K09M714A04 is a TeSys LG enclosed direct-on-line starter that combines a contactor and a circuit-breaker in one IP55 polycarbonate enclosure, rated for AC-3 motor switching at 4 kW on a 400/415 V supply. It carries a 220/230 V AC 50/60 Hz control coil and a thermal protection adjustment range of 6...10 A, making it a self-contained motor-starting package for standard-environment industrial applications.
The AC-3 utilisation category rating means the contactor inside is tested for switching squirrel-cage motors — making and breaking currents during start and stop — not just resistive loads. At 400/415 V it handles a 4 kW motor; at 220/230 V that drops to 1.5 kW, so match your line voltage to the motor nameplate. The thermal protection range of 6...10 A sets the overload relay's trip band. If your motor's full-load current falls inside that window, this starter provides integral overcurrent protection without a separate overload block. IP55 and IK07 mean the enclosure is dust-protected and hose-down resistant, and can withstand a 0.5 J impact — suitable for floor-mounted or wall-mounted installs near washdown areas, not for submerged or high-pressure cleaning zones.
