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.","metaTitle":"TeSys LG1D182P721 Enclosed DOL Starter, 17-23 A, 230 V AC","metaDescription":"Schneider TeSys LG1D182P721 enclosed DOL starter, 17-23 A thermal range, 230 V AC coil, IP55, AC-3.

For a functional equivalent, compare the motor power rating (4 kW at 230 V, 9 kW at 400 V), thermal protection range (17-23 A), coil voltage (230 V AC), and enclosure rating (IP55) against current TeSys LG or TeSys island enclosed starter offerings. An RFQ with your specific motor data will identify the closest current-production match."},{"question":"What are the specifications of LG1D182P721?","answer":"The LG1D182P721 is an enclosed DOL starter rated AC-3 for motor starting. Motor power: 4 kW at 230 V AC, 9 kW at 400/415 V AC. Thermal protection range: 17-23 A. Control coil: 230 V AC 50/60 Hz. Enclosure: IP55, polycarbonate, IK07 impact rating. Dimensions: 165 mm depth, 175 mm width, 165 mm height. Integrated push-button start/stop and rotary E-stop."},{"question":"Where can I buy LG1D182P721?","answer":"The LG1D182P721 is obsolete and sourced through independent distribution. Submit an RFQ for a current availability check and pricing — the part is quoted to order against your request."},{"question":"What is the difference between DOL starter and star-delta starter?","answer":"A DOL starter applies full line voltage directly to the motor windings during start, producing high inrush current (typically 6-8x FLA). A star-delta starter reduces inrush by first connecting the windings in star (lower voltage per phase) then switching to delta after a time delay. The LG1D182P721 is a DOL starter, appropriate for motors up to about 9 kW where the supply can handle the starting surge. Star-delta is used for larger motors or weak supplies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LG1D182P721","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LG1D182P721 when reusing this data.
