It mounts under a contactor (or on a rail with specific accessories) and is rated for motor power ranges from 1.1 kW up to 6 kW depending on supply voltage (200–500 V three-phase). The adjustable trip class (Class 5 through 30) lets you match the relay's thermal curve to the motor's starting profile — faster for low-inertia loads, slower for high-inertia starts. The front face carries a red push-button for stop and manual reset, a white dial for full-load current adjustment, and a red knob for automatic reset mode. Two microswitches handle the signalling circuit. The automatic reset time is fixed at 1.5 to 4 minutes, which matters for applications where you want the motor to restart without an operator visit after a trip. The motor power range covers 1.1–2 kW at 200–240 V, 2.2–3 kW at 380–440 V, 4–6 kW at 380–440 V, and 4–6 kW at 480–500 V three-phase. That means the same relay body handles a wide voltage spread — useful if your line runs mixed motor voltages. The utilisation categories include AC-1 (resistive), AC-3 (squirrel-cage motor starting), and AC-4 (plugging/inching), so it's not limited to simple starting duty. The tripping threshold is 1.25 × In per IEC 60947-4-1. The dielectric strength is 6 kV at 50 Hz (IEC 60255-5). The front face is IP20 (IEC 60529) — finger-safe but not washdown-rated. For compliance documentation, the brand provides RoHS and REACH declarations as standard for the TeSys range, plus the UL/CSA/IEC certificates listed above. No PCN or EOL notice is on record for this order code. Mounting options: under a contactor via a plate, or on a DIN rail with specific accessories. The power circuit terminals accept up to 16 mm² solid or flexible wire (no cable end), torqued to 3.1 N·m. Control circuit terminals accept 2.5 mm² at 0.8 N·m. The associated fuse rating for the signalling circuit is 5 A (gG or BS type). Dimensions: 3.1 in (79.9 mm) deep, 1.8 in (45 mm) wide, 2.9 in (72.5 mm) tall. The compact width means it fits in a standard 45 mm slot on a DIN-rail assembly, leaving room for adjacent contactors or auxiliaries.","metaTitle":"Schneider LR9D08KITD09BD TeSys thermal overload relay, 1.1–6","metaDescription":"Schneider LR9D08KITD09BD TeSys thermal overload relay, 3-pole, adjustable class 5–30, 1.1–6 kW motor range, UL/IEC/CSA listed, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Overload Relays"],"specifications":{"Depth":"3.1 in (79.9 mm)","Range":"TeSys","Width":"1.8 in (45 mm)","title":"LR9D08KITD09BD","Height":"2.9 in (72.5 mm)","Category":"US10I1222350","Standards":"UL 60947-4-1 IEC 60947-4-1 GB 14048.4 CSA C22.2","Time range":"1.5...4 min - automatic reset time","description":"Tesys motor starter kit, LC1D09BD contactor, LR9D08 thermal overload relay","Control type":"Red push-button stop and manual reset White 2 microswitches adjustable trip class Red knob automatic reset White dial full-load current adjustment","Fire resistance":"1562 °F (850 °C) IEC 60695-2-1","lifecycle_stage":"current","Flame retardance":"V1 conforming to UL 94","Mounting support":"Under contactor Plate, with specific accessories Rail, with specific accessories","Pollution degree":"3","Motor Power Range":"1.1...2 kW 200...240 V 3 phase 2.2...3 kW 380...440 V 3 phase 4...6 kW 380...440 V 3 phase 4...6 kW 480...500 V 3 phase","Poles description":"3P","Tightening torque":"Control circuit 0.8 N.m screw clamp terminals Power circuit 3.1 N.m screw clamp terminals","Motor starter type":"Direct on-line contactor","Operating altitude":"6561.68 ft (2000 m) without derating","Tripping threshold":"1.25 In IEC 60947-4-1","Dielectric strength":"6 kV 50 Hz IEC 60255-5","Protective treatment":"TH IEC 60068-2-30","Utilisation category":"AC-4 AC-1 AC-3","Contact compatibility":"M4","Contactor application":"Motor control Resistive load","Mechanical robustness":"Vibrations 10...150 Hz 6 Gn) IEC 60068-2-6 Shocks 11 ms 15 gn) IEC 60068-2-7","Nbr. of units in pkg.":"1","Associated fuse rating":"5 A gG signalling circuit 5 A BS signalling circuit","Contactor coil voltage":"24 V DC standard","Power Consumption in W":"300 mW","Thermal overload class":"Class 5...30","Connections - terminals":"Control circuit screw clamp terminals 1 0.004 in² (2.5 mm²) solid or flexible - without cable end Power circuit screw clamp terminals 1 0.02 in² (16 mm²) solid or flexible - without cable end","IP degree of protection":"Front face IP20 IEC 60529 Front face IP20 VDE 0106","Product or Component Type":"Motor starter","Electromagnetic compatibility":"Surge withstand 2 kV common mode IEC 61000-4-5 Resistance to electrostatic discharge 8 kV IEC 61000-4-2 Immunity to radiated radio-electrical interference 10 V/m IEC 61000-4-3 Immunity to fast transients 2 kV IEC 61000-4-4","[Ui] rated insulation voltage":"Power circuit 1000 V Signalling circuit 690 V","Power Pole Contact Composition":"3 NO","[Ue] rated operational voltage":"Power circuit Power circuit 10 MOhm for signalling circuit","Environment/Mechanical robustness":"Vibrations contactor open2 Gn, 5...300 Hz Vibrations contactor closed4 Gn, 5...300 Hz Shocks contactor open10 Gn for 11 ms Shocks contactor closed15 Gn for 11 ms","Ambient air temperature for storage":"-76...176 °F (-60...80 °C)","Environment/IP degree of protection":"IP20 front face IEC 60529","Thermal protection adjustment range":"0.4...2 A","Ambient Air Temperature for Operation":"23...140 °F (-5...60 °C)","Ambient air temperature for operation":"-13...158 °F (-25...70 °C) IEC 60255-8","[Uimp] rated impulse withstand voltage":"6 kV","[Ith] conventional free air thermal current":"5 A signalling circuit","Complementary/[Ue] rated operational voltage":"690 V power circuit 660 V signalling circuit","Permissible ambient air temperature around the device":"-40...158 °F (-40...70 °C) at Uc"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$95.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0100cb172b3d75cb6438a0da0bcedebe.pdf","sourceUrl":"https://www.se.com/us/en/product/LR9D08KITD09BD/tesys-motor-starter-kit-lc1d09bd-contactor-lr9d08-thermal-overload-relay/"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative in the TeSys family?","answer":"The LR9D08KITD09BD is part of the TeSys range.
