Trip curves are unaffected by ambient temperature because sensing is electronic, not bimetallic. ## Electronic sensing with phase loss detection Electronic overload release on the LR9G630 produces repeatable trip times and is inherently immune to heater aging — a real advantage on high-cycle applications. Phase loss sensitivity is built in; it will trip within seconds if one phase drops, protecting the motor from single-phasing damage. ## Reset options and enclosure rating Choose automatic or manual reset depending on process restart needs — no additional wiring for mode change, just a switch on the front. IP20 protected housing allows use inside standard panels; screw terminals are provided for 2 aux contacts (N.O./N.C.). The LR9G630 mounts directly to the contactor, saving panel space and eliminating interwiring. Overall dimensions: 8.31 in width, 5.83 in height, 7.32 in depth. ## Frequently asked questions **What trip class settings does the LR9G630 offer?** The relay offers Class 5E (fast protection for standard motors) and Class 30E (delayed trip for high-inertia loads) — both selectable via a dial on the front. **Can the reset mode be changed between automatic and manual?** Yes, a front-panel switch lets you choose automatic reset (for unattended operation) or manual reset (requires operator acknowledgment after a trip).","metaTitle":"LR9G630 TeSys Giga Overload Relay 160–630 A Class 5E/30E","metaDescription":"LR9G630 electronic overload relay, 160 to 630 A, class 5E/30E, IP20, 3-pole, phase loss sensitive, for motor protection by Schneider.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Depth":"186 mm","Range":"TeSys","Reset":"Automatic reset Manual","Width":"211 mm","Colour":"Dark grey","Height":"148 mm","Standards":"EN/IEC 60947-4-1 EN/IEC 60947-5-1 UL 60947-4-1 CSA C22.2 No 60947-4-1 JIS C8201-4-1 JIS C8201-5-1 IEC 60335-1:Clause 30.2 IEC 60335-2-40:Annex JJ UL 60335-2-40:Annex JJ UL 60335-1","Network type":"AC","Product name":"TeSys LRG","Product weight":"2.9 kg","Protection type":"Ground fault protection - tripping time adjustment: 0...1 s - for alarm circuit conforming to IEC 60947-4-1 Ground fault protection - tripping time adjustment: 0...1 s - for alarm circuit conforming to UL 60947-4-1 Phase loss - tripping time adjustment: 0...4 s - for alarm circuit Phase imbalance - tripping time adjustment: 0...5 s - for alarm circuit conforming to IEC 60947-4-1 Phase imbalance - tripping time adjustment: 0...5 s - for alarm circuit conforming to UL 60947-4-1","Surge withstand":"4 kV","lifecycle_stage":"current","Local signalling":"LED Trip indicator","Mounting support":"Direct on contactor Plate","Device short name":"LR9G","Network frequency":"30...60 Hz 100 Hz","Relay application":"Motor protection","Tightening torque":"58 N.m","Tripping threshold":"1.125 +/- 0.07 In conforming to IEC 60947-4-1","Overvoltage category":"III","Protective treatment":"TH","Mechanical durability":"7000 cycles","Mechanical robustness":"Vibrations 5...300 Hz 6 gn contactor open Shocks 15 gn 11 ms contactor closed","Thermal overload class":"Class 5E...30E conforming to IEC 60947-4-1","Connections - terminals":"Power circuit: bar - busbar cross section: 50 x 10 mm Power circuit: lugs-ring terminals 1 300 mm² Control circuit: push-in 1 0.2...2.5 mm² - cable stiffness: solid stranded without cable end Control circuit: push-in 1 0.25...2.5 mm² - cable stiffness: flexible with cable end Control circuit: push-in 2 0.5...1.0 mm² with cable end","IP degree of protection":"IP2X front face with shrouds conforming to IEC 60529 IP2X front face with shrouds conforming to VDE 0106","Product or component type":"Electronic thermal overload relay","Adjustment of dial setting":"-25...60 °C","[Uc] control circuit voltage":"24...500 V AC 50/60 Hz 24...250 V DC","Contacts type and composition":"1 NO + 1 NC","Electromagnetic compatibility":"EMC immunity conforming to IEC 60947-4-1 Emission tests criteria A conforming to IEC 60947-4-1 Immunity to radiated radio-electrical interference - test level: 20 V/m conforming to EN/IEC 61000-4-3 Voltage dips and interruptions immunity test conforming to SEMI F47","[Ue] rated operational voltage":"1000 V AC 50/60 Hz","Ambient air temperature for storage":"-60...80 °C","Thermal protection adjustment range":"160...630 A","Ambient air temperature for operation":"-25...60 °C","[Uimp] rated impulse withstand voltage":"8 kV","[Ith] conventional free air thermal current":"5 A","Permissible ambient air temperature around the device":"-40...60 °C at Uc"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cddc1d1804066f8cf2c18f19cea6fadc.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/LR9G630/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LR9G630","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/LR9G630 when reusing this data.
