The LG1D182P721 is an enclosed direct-on-line starter from the TeSys LG family, combining a contactor, switch disconnector, and circuit-breaker in a single IP55 polycarbonate enclosure. Motor power ratings are 4 kW at 220/230 V AC and 9 kW at 400/415 V AC, so the part fits small-to-medium pump, fan, or conveyor drives within that power band. The thermal protection adjustment range of 17-23 A sets the overload trip threshold; set it to the motor's full-load amps, not the starter's maximum. The push-button start (white I), stop (black O), and rotary emergency stop (red) are integrated, so no separate pilot-device enclosure is needed. IP55 means the enclosure is dust-protected and hose-down resistant, suitable for washdown areas or outdoor installation under a canopy. The polycarbonate housing is impact-rated to IK07, handling light mechanical knocks on the line.
Deployment context
This enclosed starter is a self-contained motor-starting package for a single motor load. Mount it near the motor or in a local control panel; the IP55 enclosure allows wall-mounting without a separate cabinet in clean, dry indoor environments or sheltered outdoor locations. Cable entries are 4 knockouts — 2 x Pg 13 and 2 x Pg 16 at both top and bottom — sized for standard motor and control cables. The integrated push buttons and E-stop eliminate the need for a separate control station, saving panel space and wiring.
