It provides overcurrent protection by responding to heat generated by excessive current draw, helping prevent motor burnout and equipment damage. Measuring 2.5 inches in length, 1.2 inches in width, and 0.8 inches in height, the B0.63 is a compact replacement component weighing 0.04 pounds. It is installed by licensed electricians and industrial maintenance technicians as part of motor starter assemblies in commercial and light industrial settings.\u003c\/p\u003e\u003cp\u003eThe B0.63 thermal unit is suited for use in motor starter and contactor assemblies where overload protection is required. Typical applications include HVAC compressor motor starters, pump motor controls, and general-purpose industrial motor control centers. It is a direct-replacement accessory component, packaged individually for single-unit service calls or panel retrofits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThermal overload protection for contactor-based motor starter assemblies\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 2.5 x 1.2 x 0.8 inches for space-constrained enclosures\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.04 pounds for easy handling during installation\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging supports one-for-one field replacement\u003c\/li\u003e\n\u003cli\u003eOEM-style accessory designed to fit contactor assemblies requiring thermal unit components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement thermal unit for SQUARE D contactor and motor starter assemblies that accept B-series thermal overload elements.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThermal overload units should be installed by a qualified electrician in accordance with NEC guidelines and local electrical codes. De-energize and lock out the control panel before removing or installing any contactor accessory. Verify the thermal unit rating matches the full-load amperage of the motor being protected before reinstalling the assembly. Do not bypass or substitute thermal units with unrated components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContactor Accessory Type\u003c\/strong\u003e: Thermal Unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: SQUARE D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B0.63\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51543571104050,"sku":"B0.63","price":63.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee8e1480df75532d17c7adc66db20e01_3f2c3eee-8c3a-46d4-9306-478cdbaab85a.jpg?v=1785920480","url":"https:\/\/voomisupply.com\/products\/square-d-b0-63-contactor-thermal-overload-unit","provider":"Voomi Supply","version":"1.0","type":"link"}
