The Schneider TeSys LG enclosed DOL starter LG7K09N714A12 is a direct-on-line motor starter in an IP55 polycarbonate enclosure, rated for 4 kW at 400/415 V AC in AC-3 duty. Thermal protection is adjustable 6-10 A via the built-in circuit-breaker, and the control circuit runs on 400/415 V AC 50/60 Hz. The assembly includes a contactor, circuit-breaker, and short-circuit signalling block, plus a push-button start (white I), stop (black O), and red mushroom-head emergency stop — all pre-wired inside the enclosure. The IP55 rating means the enclosure is dust-protected and resists water jets from any direction — suitable for washdown areas or outdoor installation under a canopy. The polycarbonate housing gives IK07 impact resistance, so it survives incidental tool bumps on the panel face.
This starter is sized for a 4 kW, 400 V three-phase motor in AC-3 switching duty — that covers most standard 4-pole induction motors on pumps, fans, and small conveyors. The 6-10 A thermal adjustment range matches motors drawing roughly 7-9 A full-load at 400 V. Four cable entries (2x Pg 13 + 2x Pg 16 top and bottom) give flexibility for incoming supply and motor leads in a panel or standalone box. Enclosure dimensions are 165 mm high, 175 mm wide, 177 mm deep — compact enough for a wall-mount or machine-side bracket. The polycarbonate material is lighter than steel and won't corrode in humid environments.
The LG7K09N714A12 is designed to IEC 60204-1 (safety of machinery — electrical equipment) and IEC 60947-4-1 (contactors and motor-starters). These are the core standards for industrial motor control in Europe and most export markets. The IK07 impact rating and IP55 ingress protection are tested per IEC 60529.
