It provides motor branch-circuit overload protection by detecting sustained overcurrent conditions and tripping the associated contactor before damage occurs. The relay uses a bimetal thermal sensing element to respond to heat buildup caused by excess current draw. Trip Class 10A defines the maximum trip time under locked-rotor conditions, making this relay suited for loads that start quickly. Licensed electricians and industrial maintenance technicians typically install this device as part of a motor starter assembly.\u003c\/p\u003e\u003cp\u003eThe LR3D07 is designed for use in motor control applications where an IEC-style contactor and overload relay combination is required. It is specified for use with the LC1D09 through LC1D38 family of contactors, covering a range of small to mid-size motor starters in both residential and light commercial or industrial control panels. Typical install scenarios include pump motor starters, fan motor starters, and conveyor drive assemblies where motor protection is required by electrical codes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method provides reliable overload detection without electronic components\u003c\/li\u003e\n\u003cli\u003eAdjustable current range of 1.6 to 2.5 amps covers a range of small motor loads\u003c\/li\u003e\n\u003cli\u003e690 VAC rating supports use on standard single-phase and three-phase distribution systems\u003c\/li\u003e\n\u003cli\u003eTrip Class 10A response curve suited for normal-inertia motor loads\u003c\/li\u003e\n\u003cli\u003eCompact form factor mounts directly to compatible IEC contactors without additional hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSpecified for use with LC1D09 and LC1D38 IEC contactors as an overload relay module in motor starter assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the motor control panel before mounting or wiring the relay. Set the current adjustment dial to match the full-load amperage of the motor being protected before energizing. Do not bypass the overload relay or manually reset it without first identifying and correcting the cause of the trip.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 1.6 to 2.5 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 690 VAC\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: 2.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.1 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: LR3D07\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51539577733426,"sku":"LR3D07","price":118.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/958788e1546e74dda48b678ab52acf1d_2fac1c20-54ab-4f81-a675-d6452c5298f8.jpg?v=1785843392","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lr3d07-thermal-iec-overload-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
