It is supplied from 200-240 V AC and adds adjustable O-TIME and D-TIME dials plus phase-failure detection that a plain bimetallic relay cannot match.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLR97D38M7\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\u003eRange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTeSys D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDevice Short Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLR97\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eElectronic overcurrent relay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLC1D25...D38\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Us] Rated Supply Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e200-240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThermal Protection Adjustment Range (LOAD Dial)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20…38 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTripping Threshold\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20…34 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eO-Time Dial (Overcurrent Duration)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.3…10 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eD-Time Dial (Starting Duration)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.5…30 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhase Failure Sensitivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 3 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eContacts Type and Composition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 C\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Ue] Rated Operational Voltage (Power Circuit)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e690 V AC (IEC 60947-4-1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e[Uimp] Rated Impulse Withstand Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSurge Withstand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 kV (IEC 61000-4-5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eReset\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eManual or automatic (120 s fixed), electrical reset\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSignalling Function\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 LEDs (Run \/ Trip)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting Support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDirect on contactor or rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIP Degree of Protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP20 (IEC 60529)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient Air Temperature for Operation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-25…60 °C (IEC 60947-4-1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.172 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGOST\u003c\/li\u003e\n\u003cli\u003eCSA\u003c\/li\u003e\n\u003cli\u003eUL\u003c\/li\u003e\n\u003cli\u003eIEC 60947\u003c\/li\u003e\n\u003cli\u003eIEC 60255-6\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eThe 20-38 A LOAD dial covers LC1D25...D38 contactors; set it to the motor's actual full-load current rather than the top of the range so the 20-34 A tripping threshold protects the winding instead of the contactor's maximum rating. The D-TIME dial (0.5-30 s) should match the motor's real starting time so the relay rides through inrush without nuisance tripping, while O-TIME (0.3-10 s) sets how long a steady-state overcurrent above 3×LOAD is tolerated before the relay opens its 1 C\/O contact. Pick the 200-240 V AC variant to match the control transformer already feeding the rest of the panel; the current-setting dials are identical across every supply-voltage variant in this range.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50230486368539,"sku":"LR97D38M7","price":114.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-lr97d38m7-tesys-d-overload-relay.jpg?v=1790901274","url":"https:\/\/stoklink.com\/products\/schneider-electric-lr97d38m7-tesys-d-overload-relay","provider":"Stoklink","version":"1.0","type":"link"}
