It protects motors and connected loads from sustained overcurrent conditions by detecting heat buildup caused by excess current draw. When the thermal element trips, it interrupts the control circuit and prevents damage to the motor windings. This relay is a Trip Class 10A device, meaning it trips within 10 seconds under a standard 7.2x overload test condition. Licensed electricians and industrial maintenance technicians install this relay as part of a motor starter assembly in panel boards, motor control centers, and control enclosures.\u003c\/p\u003e\u003cp\u003eThe LR3D332 is designed for use with LC1D40A and LC1D65A contactors, making it a direct companion component in Schneider Electric IEC motor starter configurations. It suits three-phase motor protection applications in commercial and industrial settings where IEC-standard motor control equipment is specified. Typical installations include pump motor starters, conveyor drives, fan motor assemblies, and other machinery requiring reliable overcurrent protection at voltages up to 690 VAC.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal sensing method detects overcurrent through heat accumulation in the bimetal element\u003c\/li\u003e\n\u003cli\u003eTrip Class 10A rating for fast response under heavy overload conditions\u003c\/li\u003e\n\u003cli\u003eCurrent range of 23 to 32 amps with adjustable set point across the full range\u003c\/li\u003e\n\u003cli\u003eRated up to 690 VAC for compatibility with high-voltage IEC motor control systems\u003c\/li\u003e\n\u003cli\u003eDirect mount to LC1D40A and LC1D65A contactors without additional hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Schneider Electric LC1D40A and LC1D65A contactors as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel or motor control center before mounting or wiring the relay. Set the overload adjustment dial to match the motor full-load amperage (FLA) as listed on the motor nameplate. Do not bypass the overload relay or defeat the trip mechanism during testing or commissioning.\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: 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: 2.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.93 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: LR3D332\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51544134811954,"sku":"LR3D332","price":165.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/193e397a730351fc7a5630c81f225f9c_7eecb35c-b868-4061-96c9-785d6c3bb861.jpg?v=1785924635","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lr3d332-thermal-overload-relay-23-32a","provider":"Voomi Supply","version":"1.0","type":"link"}
