The Schneider Electric TeSys LG1D182N720 is an enclosed direct-on-line (DOL) starter combining a contactor, switch disconnector, and circuit-breaker in a single IP55 polycarbonate enclosure. It is rated for AC-3 motor switching duty and carries a thermal protection adjustment range of 13 to 18 A.
The 13...18 A thermal protection range sets the overload relay trip point — sized for motors drawing full-load current in that band. The 415 V AC coil means the starter picks up on a 415 V control circuit at 50/60 Hz; verify your control voltage matches before wiring. Motor power capability depends on line voltage: 4 kW at 220/230 V AC, 7.5 kW at 400/415 V AC, and 9 kW at 440 V AC — all at 50/60 Hz. The AC-3 utilisation category confirms it is rated for starting squirrel-cage motors and switching them off during running. The IP55 enclosure with IK07 impact resistance makes it suitable for washdown areas and dusty industrial environments — the polycarbonate housing stands up to mild chemical exposure and hose-directed water.
