It protects three-phase and single-phase motor loads from sustained overcurrent conditions by detecting heat buildup in the bimetal sensing elements. When current exceeds the set threshold, the relay trips and interrupts the control circuit before the motor or downstream equipment sustains damage. Rated Trip Class 20, it is designed for applications where a moderate delay on trip is appropriate. Licensed electricians and industrial maintenance technicians install and configure this relay as part of a motor starter assembly.\u003c\/p\u003e\u003cp\u003eThe LR2D3553 is intended for use with LC1D80 and LC1D95 contactor bodies, making it a direct-mount accessory in those motor starter configurations. It is suited for commercial and industrial motor control applications including pump motors, fan motors, conveyor drives, and compressor loads where IEC-style motor protection is required. The Trip Class 20 rating accommodates motors with higher inrush characteristics during startup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method detects sustained overcurrent without electronic components\u003c\/li\u003e\n\u003cli\u003eTrip Class 20 rating provides appropriate trip delay for motors with high inrush current\u003c\/li\u003e\n\u003cli\u003eWide current adjustment range of 23 to 32 amps covers multiple motor frame sizes\u003c\/li\u003e\n\u003cli\u003eRated for up to 690 VAC for compatibility with international and domestic motor control panels\u003c\/li\u003e\n\u003cli\u003eDirect mount design pairs with LC1D80 and LC1D95 contactors without additional wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Schneider Electric LC1D80 and LC1D95 IEC contactors as a direct-mount thermal overload relay in motor starter assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. Disconnect and lock out all power to the motor control panel before mounting or adjusting this relay. Set the current adjustment dial to match the full-load amperage of the protected motor after installation. Do not exceed the rated voltage or current range of the relay.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 23 to 32 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: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: LR2D3553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51540706328882,"sku":"LR2D3553","price":203.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22a3a6ae023c25c61d099988aaf31058.jpg?v=1785862496","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lr2d3553-thermal-iec-overload-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
