The Schneider Electric TeSys LR9D32KITD09BD is a direct on-line motor starter with integrated thermal overload protection, designed for three-phase squirrel-cage motors. It covers motor power from 1.1 kW to 6 kW across supply voltages of 200–240 V and 380–500 V, three-phase. The 24 V DC coil is standard, and the overload relay is adjustable from Class 5 to Class 30, so you can match the trip curve to the motor's starting characteristic — useful for high-inertia loads like fans or conveyors that need a longer acceleration window.
The adjustable overload class (5…30) means the thermal memory can be set to trip faster (Class 5) for pumps or slower (Class 30) for high-inertia starts, without changing hardware. The tripping threshold is 1.25 × Iₙ per IEC 60947-4-1 — that's the standard thermal curve, not a custom one. The unit is rated for utilisation categories AC-1 (resistive), AC-3 (squirrel-cage motor starting/running), and AC-4 (plugging/reversing), so it handles both normal motor duty and frequent reversing applications.
The LR9D32KITD09BD carries UL 60947-4-1, IEC 60947-4-1, CSA C22.2, and GB 14048.4 approvals, so it's accepted in North American, European, and Chinese installations. Dielectric strength is 6 kV at 50 Hz per IEC 60255-5, and the enclosure material is V-1 flame retardant per UL 94. TH protective treatment per IEC 60068-2-30 means it's tested for damp-heat cycling — no condensation issues in a standard panel.
