This handle interfaces directly with the operating mechanism to provide manual control over circuit breaker switching, allowing technicians to operate breakers from outside an enclosure without direct contact with live components. The unit measures 8.8 inches in length, 6.7 inches in width, and 4.6 inches in height, and ships as a single-piece replacement accessory weighing 2.55 pounds.\u003c\/p\u003e\n\u003cp\u003eThis handle is intended for use in industrial electrical panel and switchgear installations where a SQUARE D 9421LM1 or LX7 Operating Mechanism is already installed. Typical applications include motor control centers, distribution panels, and enclosed circuit breaker assemblies where external operator access is required. Installation is performed by licensed electricians working on industrial or commercial electrical systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned as a direct replacement handle for SQUARE D 9421LM1 or LX7 Operating Mechanisms\u003c\/li\u003e\n  \u003cli\u003eEnables external manual operation of enclosed circuit breakers\u003c\/li\u003e\n  \u003cli\u003eSingle-piece accessory with no field fabrication required\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 8.8 inches long, 6.7 inches wide, 4.6 inches tall\u003c\/li\u003e\n  \u003cli\u003eShips individually packaged for single-unit replacement jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the SQUARE D 9421LM1 Operating Mechanism or LX7 Operating Mechanism as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before removing or installing the operating mechanism handle. Verify that the handle is fully seated and properly aligned with the operating mechanism before restoring power. Do not force the handle into position, as misalignment can damage the mechanism linkage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Operating Mechanism Handle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.55 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: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9421LH8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542897721650,"sku":"9421LH8","price":111.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02a15c7472b07582ea3c909fd3e315a2.jpg?v=1785910237","url":"https:\/\/voomisupply.com\/products\/square-d-9421lh8-circuit-breaker-operating-mechanism-handle","provider":"Voomi Supply","version":"1.0","type":"link"}
