It uses thermal sensing to detect sustained overcurrent conditions and trip the connected contactor before motor windings or downstream equipment sustain heat damage. Trip Class 10A defines the tripping time curve, making this relay suited for standard motor loads that require protection without nuisance tripping during normal inrush. Licensed electricians and industrial maintenance technicians are the primary installers of this device in motor starter assemblies and control panels.\u003c\/p\u003e\n\u003cp\u003eThis relay is designed for use in IEC-style motor starter assemblies, typically protecting three-phase motors in light-duty industrial and commercial applications. Its compact form factor and direct-mount design allow it to integrate cleanly into a starter block without additional wiring between the overload relay and contactor. Confirmed compatible contactors include the LC1D09 and LC1D38. It is appropriate for applications where motor current draw falls consistently in the 0.4 to 0.63 amp operating range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThermal sensing method provides reliable overcurrent detection for motor protection\u003c\/li\u003e\n  \u003cli\u003eAdjustable current range of 0.4 to 0.63 amps covers light motor load applications\u003c\/li\u003e\n  \u003cli\u003eRated to 690 volts AC for compatibility with international and domestic supply voltages\u003c\/li\u003e\n  \u003cli\u003eTrip Class 10A curve balances fast fault response with tolerance for motor starting inrush\u003c\/li\u003e\n  \u003cli\u003eDirect-mount design mates with LC1D-series IEC contactors without external wiring\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions support installation in space-constrained control enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed for use with the LC1D09 and LC1D38 IEC contactors.

De-energize and lock out the full panel before mounting or adjusting the relay. Set the current dial to match the motor full-load ampere rating shown on the motor nameplate after the relay is mechanically secured to the contactor. Do not bypass or jumper the overload relay contacts during commissioning testing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 0.4 to 0.63 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 690 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Class\u003c\/strong\u003e: 10A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensing Method\u003c\/strong\u003e: Thermal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHNEIDER ELECTRIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LRD04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542812197170,"sku":"LRD04","price":108.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bce82c92a6e59668a878514d20e70e15_7e028b38-e0e6-44c3-9e8f-f4f4d04f10f2.jpg?v=1785908109","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lrd04-thermal-iec-overload-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
