The Schneider Electric TeSys LG1K065Q705A37 is an enclosed direct-on-line starter — a single box that bundles a contactor, a circuit-breaker, and a switch disconnector together with push-button and emergency-stop controls. It's built for AC-3 motor duty and carries thermal protection adjustable from 0.63 to 1 A, so it's sized for small motors in that current band.
The 0.63-1 A thermal protection adjustment range is the key spec for selection — it governs which motor this starter protects. At the low end (0.63 A) it covers a roughly 0.12 kW motor at 230 V; at the high end (1 A) it handles up to 0.25 kW at 400/415 V. If your motor's full-load current falls outside that band, this isn't the right unit. The AC-3 utilisation category means it's rated for starting squirrel-cage motors — switching them on and off under load, not just isolating a dead circuit. That's the standard category for DOL starters feeding induction motors. IP55 and IK07 mean the enclosure keeps out dust and water jets and can take a moderate mechanical knock — 0.5 J impact. That's suitable for washdown areas and general industrial floors, but not submersion or heavy blows.
This is a safety-rated enclosed starter — the mushroom-head emergency stop and push-button start/stop are built in, so it's ready to wire into a machine's safety circuit without adding separate control stations. It's common on conveyors, pumps, fans, and small process machines where you need local start/stop and an emergency stop at the motor.
