It operates on AC or DC control circuits up to 1000 V and carries 1 NO + 1 NC auxiliary contacts. Ambient temperature compensation is active from -20 to 60 °C, and the relay withstands 6 Gn vibration and 15 Gn shock, keeping the trip threshold stable on mobile or high-vibration equipment. ## Applications Designed for three-phase motor protection in conveyors, pumps, fans, and compressors. ## Compliance & certifications Certified to IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, CCC, EAC, BV, DNV-GL, LROS, ATEX (INERIS), and UKCA. Suitable for global panel builds and hazardous-area motor circuits. Power circuit terminals accept 4–35 mm² solid or flexible conductors; control circuit terminals accept 1–2.5 mm². Torque to 9 N·m (power) and 1.7 N·m (control). Mounting options include direct under-contactor, plate, or DIN rail with accessories. ## Dimensions & environment Dimensions are 114.3 mm deep × 71.12 mm wide × 81.28 mm high. IP20 rated for in-cabinet use. Storage temperature range -60 to 70 °C.","metaTitle":"Schneider LR3D3322 TeSys Deca thermal overload relay, 17–25 A, Class 10A","metaDescription":"Schneider LR3D3322 TeSys Deca non-differential thermal overload relay, 17–25 A, Class 10A, 1000 V, IP20, UL/CSA/CCC certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Depth":"4.5 in (115 mm)","Range":"TeSys","Width":"2.8 in (70 mm)","Height":"3.2 in (81 mm)","Category":"US10I1222347","Standards":"EN/IEC 60947-4-1 EN/IEC 60947-5-1 UL 60947-4-1 UL 60947-5-1 CSA C22.2 No 60947-4-1 CSA C22.2 No 60947-5-1 GB/T 14048.4 GB/T 14048.5 EN 50495","Control type":"Red push-button stop Blue push-button reset","Network type":"AC DC","Product name":"TeSys LRD TeSys Deca","lifecycle_stage":"current","Flame retardance":"V1 conforming to UL 94","Mounting support":"Plate, with specific accessories Rail, with specific accessories Under contactor","Device short name":"LR3D","Network Frequency":"0...400 Hz","Relay application":"Motor protection","Tightening torque":"Control circuit 15.05 lbf.in (1.7 N.m) screw clamp terminals Power circuit 79.7 lbf.in (9 N.m) screw clamp terminals","Climatic withstand":"IACS E10","Tripping threshold":"1.14 +/- 0.06 Ir IEC 60947-4-1","Dielectric strength":"2.2 kV 50 Hz IEC 60947-1","Permissible current":"0.72 A 500 V AC-15 signalling circuit 0.06 A 440 V DC-13 signalling circuit","Mechanical robustness":"Vibrations6 Gn IEC 60068-2-6 Shocks15 Gn for 11 ms IEC 60068-2-7","Nbr. of units in pkg.":"1","Associated fuse rating":"4 A gG for signalling circuit 4 A BS for signalling circuit","Thermal overload class":"Class 10A IEC 60947-4-1","Connections - terminals":"Power circuit screw clamp terminals 1 0.006...0.05 in² (4...35 mm²) flexible without cable end Power circuit screw clamp terminals 1 0.006...0.05 in² (4...35 mm²) flexible with cable end Power circuit screw clamp terminals 1 0.006...0.05 in² (4...35 mm²) solid without cable end Control circuit screw clamp terminals 2 0.002...0.004 in² (1...2.5 mm²) flexible without cable end Control circuit screw clamp terminals 2 0.002...0.004 in² (1...2.5 mm²) flexible with cable end Control circuit screw clamp terminals 2 0.002...0.004 in² (1...2.5 mm²) solid without cable end","IP degree of protection":"IP20 conforming to IEC 60529","Temperature compensation":"-4...140 °F (-20...60 °C)","Phase failure sensitivity":"Tripping current 130 % of Ir on two phase, the last one at 0","Product or Component Type":"Non differential thermal overload relay","Auxiliary contact composition":"1 NO + 1 NC","[Ui] rated insulation voltage":"Power circuit 1000 V IEC 60947-4-1 Power circuit 600 V CSA Power circuit 600 V UL","[Ue] rated operational voltage":"1000 V AC 0...400 Hz power circuit IEC 60947-4-1","Ambient Air Temperature for Storage":"-76...158 °F (-60...70 °C)","Thermal protection adjustment range":"17...25 A","Ambient air temperature for operation":"-4...140 °F (-20...60 °C) without derating IEC 60947-4-1","[Uimp] rated impulse withstand voltage":"6 kV IEC 60947-1","[Ith] conventional free air thermal current":"5 A signalling circuit"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$156.52","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c8415c2a163166cf229da2885d083aee.pdf","sourceUrl":"https://www.se.com/vn/en/product/LR3D3322/tesys-deca-thermal-overload-relays17-25aclass-10afor-use-with-unbalanced-loads/","alternativesUrl":"https://aoctrl.com/api/mcp/products/LR3D3322/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LR3D3322","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LR3D3322 when reusing this data.
