The Schneider Electric TeSys LG1D182M720 is an enclosed direct-on-line (DOL) starter that integrates a contactor, switch disconnector, and circuit-breaker into one IP55 polycarbonate enclosure — a single assembly for motor starting and protection in a safe, guarded package. Rated for AC-3 duty, it handles 4 kW at 220/230 V AC, 7.5 kW at 400/415 V AC, and 9 kW at 440 V AC — covering the common three-phase motor sizes for pumps, fans, and small conveyors on 50/60 Hz mains. The thermal protection adjustment range of 13-18 A lets you dial in the overload setting to match the motor full-load current, protecting against sustained overcurrent without nuisance tripping.
Controls and safety integration
The front panel carries a white push-button start (I), a black push-button stop (O), and a red rotary-handle emergency stop — a complete operator station integrated into the starter body, saving panel space and wiring. With a safety application designation and compliance to IEC 60204-1 (machinery safety) and IEC 60947-4-1 (contactors and motor-starters), this unit is suited for guarding circuits where an E-stop and local control are required at the machine. The IP55 enclosure and IK07 impact resistance mean it can be mounted directly on the machine frame in washdown or dusty environments — no separate panel cabinet needed.
Dimensions and cable entry
Cable entries: four knockouts on top (two Pg 13 + two Pg 16) and four on the bottom (same pattern), giving flexibility for top/bottom cable routing without drilling.
