It provides motor overcurrent and phase-loss protection by sensing thermal conditions across all three poles and tripping when sustained overload is detected. Designed to Trip Class 20, the relay allows motors with higher inertia loads sufficient start-up time before tripping on a fault. The LR3D14L is sized for NEMA 00 through 1 contactor frames and is a direct-mount accessory installed by licensed electricians or qualified controls technicians on motor-starter assemblies.\u003c\/p\u003e\n\u003cp\u003eThis relay is suited for light-duty industrial and commercial motor control applications where a three-phase motor must be protected against overload conditions. Common installations include small pump motors, fan motors, and conveyor drives operating within the 7 to 10 amp service range. The LR3D14L mounts directly to compatible LC1D-series contactors, making it a standard component in assembled NEMA motor starter panels. It is appropriate for both new installations and field replacement of worn or failed overload elements in existing starter assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-pole thermal sensing provides balanced overload protection across all phases\u003c\/li\u003e\n  \u003cli\u003eAdjustable trip range of 7 to 10 amps covers a range of small motor applications\u003c\/li\u003e\n  \u003cli\u003eTrip Class 20 rating accommodates motors with longer acceleration times under load\u003c\/li\u003e\n  \u003cli\u003eRated to 690 VAC for compatibility with both 480-volt and higher-voltage industrial systems\u003c\/li\u003e\n  \u003cli\u003eDirect-mount design attaches to LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, and LC1D38 contactors without additional hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for direct mounting on Schneider Electric LC1D-series contactors: LC1D09, LC1D12, LC1D18, LC1D25, LC1D32, and LC1D38.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out all power to the motor control panel before mounting or replacing the overload relay. Verify that the motor full-load amperage falls within the relay adjustment range before setting the trip dial. Do not bypass or jumper the overload contacts during commissioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Size\u003c\/strong\u003e: 00-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 7 to 10 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: 20\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: 2.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: LR3D14L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541982314802,"sku":"LR3D14L","price":98.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5474b6c95bac6ccd1239c04849fd2433.jpg?v=1785888829","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lr3d14l-thermal-overload-relay-7-10a","provider":"Voomi Supply","version":"1.0","type":"link"}
