As a bimetallic overload relay, the LRD03 safeguards three-phase and single-phase motors against sustained overcurrents, phase failure, and overheating — making it an essential component in motor starter assemblies paired with TeSys Deca contactors. Engineered for industrial panel builders and OEMs, the LRD03 offers precise current setting and robust thermal trip performance in a compact DIN-rail compatible format.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU \/ Reference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLRD03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTeSys Deca\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLRD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eThermal Overload Relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent Adjustment Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.25–0.4 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.124 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eApplications \u0026amp; Use Cases\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Starter Assemblies:\u003c\/strong\u003e Pairs directly with TeSys Deca contactors for compact, IEC-compliant motor starters in control panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Power Motor Protection:\u003c\/strong\u003e Ideal for protecting small three-phase motors operating at low current ratings in conveyors, pumps, fans, and HVAC equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Machine Building:\u003c\/strong\u003e Suitable for machine builders requiring reliable thermal protection in a standardised, interchangeable relay format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Automation Panels:\u003c\/strong\u003e Used in MCC (Motor Control Centre) builds where space-efficient, bimetallic overload protection is required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat contactor does the LRD03 mount to?\u003c\/strong\u003e The LRD03 is designed to plug directly onto TeSys Deca series contactors (LC1D \/ LC1E family), enabling tool-free assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes the LRD03 support manual and auto reset?\u003c\/strong\u003e TeSys Deca thermal relays typically support both manual and automatic reset modes; select the reset mode appropriate for your application's safety requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is the current setting range of the LRD03?\u003c\/strong\u003e The LRD03 covers a 0.25–0.4 A adjustment range, making it suitable for very small motors and low-current loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs the LRD03 suitable for phase failure detection?\u003c\/strong\u003e TeSys Deca overload relays provide phase failure sensitivity, protecting motors against single-phasing conditions.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50230511173915,"sku":"LRD03","price":39.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lrd03-thermal-overload-relay_8b9a7e6c-902b-434b-887a-122f535a9d8e.jpg?v=1777166237","url":"https:\/\/stoklink.com\/products\/schneider-lrd03-tesys-deca-thermal-overload-relay","provider":"Stoklink","version":"1.0","type":"link"}
