The Schneider TeSys LG7K06R707 is an enclosed direct-on-line starter combining a contactor and circuit-breaker in a single IP55 polycarbonate enclosure. It is rated for AC-3 motor switching and covers a thermal protection adjustment range of 1.6 to 2.5 A, making it a straightforward fit for small motor loads up to 1.1 kW at 440 V AC. The 440 V AC coil voltage matches common three-phase line supplies in many industrial panels, so no separate control transformer is needed when the motor supply and coil share the same voltage.
The AC-3 utilisation category means this starter is rated for starting and disconnecting squirrel-cage motors — the most common duty for a DOL starter. The motor power ratings are 0.37 kW at 220/230 V AC, 0.75 kW at 400/415 V AC, and 1.1 kW at 440 V AC, all at 50/60 Hz. Match your motor's nameplate full-load current to the 1.6…2.5 A thermal adjustment range; that window determines the actual motor protection, not the kW figure alone. Compliance with IEC 60947-4-1 (the standard for contactors and motor-starters) and IEC 60204-1 (safety of machinery — electrical equipment) covers the two main regulatory gates for a starter installed in a machine control panel.
Enclosure and wiring
The polycarbonate material is lighter than steel and resists corrosion in humid environments. Cable entry is provided via four knockouts: two Pg 13 and two Pg 16 on both top and bottom faces. That gives flexibility for incoming supply and outgoing motor cables without drilling extra holes. The push-button controls on the front cover include a white start button, a black stop button, and a red mushroom-head emergency stop — all labelled per standard machine-control conventions.
