The Schneider Electric TeSys LG1D182Q7 is an enclosed direct-on-line starter from the TeSys LG range, rated for 18 A in AC-3 duty (motor switching) with a 380 V AC 50/60 Hz control coil. It integrates a contactor and switch disconnector in one IP55 polycarbonate enclosure, with a separate circuit-breaker ordered alongside. The push-button start/stop and red rotary emergency stop are built in, so it arrives as a ready-to-wire motor-start package for a panel or machine.
The 18 A AC-3 rating is the motor-switching current — it governs the maximum induction motor load this starter can handle under starting and running conditions. The 380 V AC coil voltage means the control circuit must supply that voltage at 50 or 60 Hz; it is not a 24 VDC or 110 V option. IP55 means the enclosure is dust-protected and can withstand water jets from any direction — suitable for washdown areas or outdoor installation under cover. IK07 impact resistance (1 joule) means it survives accidental tool drops or bumping on the line. The polycarbonate housing is non-corrosive and lighter than metal, but check the ambient temperature range if mounted near a heat source. This is a safety-rated device (: Device application = Safety). The integrated emergency-stop rotary handle and compliance with IEC 60204-1 (safety of machinery) mean it can serve as the disconnecting means for a motor branch circuit in a safety function, provided the upstream circuit-breaker is coordinated per the manufacturer's instructions.
Deployment context
The enclosure measures 165 mm deep, 175 mm wide, and 165 mm high, with cable entries: four top entries (2 x Pg 13 + 2 x Pg 16) and four bottom entries (same pattern). It is designed for wall or machine mounting, not DIN rail. The separate circuit-breaker (ordered as a companion part) mounts upstream; the starter itself contains the contactor and switch disconnector in one body.
