{"product_id":"schneider-electric-lr3d22-thermal-iec-overload-relay","title":"Schneider Electric LR3D22 Thermal Iec Overload Relay","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe SCHNEIDER ELECTRIC LR3D22 is a thermal IEC overload relay rated for 16 to 24 amps at up to 690 VAC. It protects motors and connected loads from sustained overcurrent conditions by sensing thermal changes in the circuit. When current exceeds the set threshold, the relay trips and interrupts the control circuit before damage occurs. Rated Trip Class 10A, it is designed for use in motor control assemblies and industrial control panels. Electricians and industrial controls technicians install this relay as part of a motor starter assembly or standalone overload protection circuit.\u003c\/p\u003e\u003cp\u003eThe LR3D22 is intended for use with LC1D25 and LC1D38 contactors, making it a direct-fit component in those motor starter configurations. It is suited for three-phase motor protection in commercial and light industrial applications where IEC-standard components are specified. The relay mounts directly to the contactor body, keeping the assembly compact. Typical applications include pump motors, fan motors, conveyor drives, and other three-phase induction motor loads requiring reliable overload protection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCurrent range: 16 to 24 amps, adjustable within that band\u003c\/li\u003e\n\u003cli\u003eVoltage rating: 690 VAC, suitable for standard three-phase distribution voltages\u003c\/li\u003e\n\u003cli\u003eTrip Class 10A for fast response to sustained overloads\u003c\/li\u003e\n\u003cli\u003eDirect-mount design compatible with LC1D25 and LC1D38 contactors\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits within standard motor starter enclosures\u003c\/li\u003e\n\u003cli\u003eIEC-standard design for use where IEC components are required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for direct use with Schneider Electric LC1D25 and LC1D38 contactors as part of an IEC motor starter assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician familiar with IEC motor starter assemblies and applicable NEC requirements. De-energize and lock out the circuit before mounting or wiring the relay. The relay mounts directly to the contactor body and connects through the contactor terminal interface. Set the current adjustment dial to match the full-load amperage of the motor being protected before energizing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 16 to 24 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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 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: LR3D22\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51540160872754,"sku":"LR3D22","price":107.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/958788e1546e74dda48b678ab52acf1d_94469ac4-1903-428c-8bed-2b8270cc7c91.jpg?v=1785847528","url":"https:\/\/voomisupply.com\/products\/schneider-electric-lr3d22-thermal-iec-overload-relay","provider":"Voomi Supply","version":"1.0","type":"link"}
