This component serves as a replacement shaft that integrates with compatible operating mechanisms to allow manual actuation of circuit breakers. At 2.08 pounds, it is a direct-fit mechanical part suited for installation by licensed electricians performing panel maintenance, equipment upgrades, or mechanism replacements in commercial and industrial electrical systems.\u003c\/p\u003e\n\u003cp\u003eThis long shaft is applied in scenarios where extended reach or indirect actuation of a circuit breaker is required, such as in enclosed panel sections or door-mounted operator assemblies. It pairs specifically with the 9421LF1 or LK1 operating mechanism and is appropriate for both new installations and service replacement work on existing switchgear or load center enclosures. Installation is typically performed by qualified electricians working on low-voltage distribution equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLong shaft configuration provides extended reach for remote or indirect breaker actuation\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct accessory to the 9421LF1 or LK1 operating mechanism\u003c\/li\u003e\n  \u003cli\u003eCompact replacement component at 2.08 pounds for straightforward field installation\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single-unit package for targeted replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the SQUARE D 9421LF1 or LK1 Operating Mechanism as a direct accessory long shaft component.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before servicing any operating mechanism or breaker assembly. Verify mechanical alignment with the mating 9421LF1 or LK1 operating mechanism before securing the shaft in place. Do not force the shaft into position, as improper seating can compromise breaker actuation reliability.\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 Long Shaft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: 9421LF1 or LK1 Operating Mechanism\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.08 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: 9421LS12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51540187971890,"sku":"9421LS12","price":66.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df274bd6bc0a60fcb2e5a210d31230d8.jpg?v=1785848417","url":"https:\/\/voomisupply.com\/products\/square-d-9421ls12-circuit-breaker-operating-mechanism-long-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
