The Schneider Electric TeSys LG7D18N720 is an enclosed DOL starter combining a contactor and circuit-breaker in an IP55 polycarbonate enclosure. It covers a 13-18 A thermal protection range, 7.5 kW at 400/415 V AC in AC-3 duty, with a 415 V AC coil. The front face carries a white start pushbutton, a black stop pushbutton, and a red mushroom-head emergency stop — so it's a complete operator station plus motor protection in one enclosure. Cable entries are 2 x Pg 13 and 2 x Pg 16 at both top and bottom, which gives you some flexibility on gland sizing.
Lifecycle status — this part is obsolete
The evidence does not list a direct official successor order code from Schneider. If you're planning a replacement, you'll need to evaluate a current TeSys or TeSys island starter that matches your motor kW, coil voltage, and enclosure rating — the specs above (13-18 A thermal, 415 V AC coil, IP55) are the critical fit parameters to carry forward.
The thermal adjustment range of 13-18 A sets overload protection to match motor full-load current. The 415 V AC coil requires that control voltage.
