It provides the mechanical linkage needed to extend handle reach on enclosed or remotely mounted circuit breaker installations. Licensed electricians and panel technicians install this component during breaker enclosure retrofits, switchboard upgrades, or replacement service work. The long shaft design accommodates installations where standard-length shafts cannot reach the operating mechanism, maintaining reliable manual switching action without compromising enclosure integrity.\u003c\/p\u003e\n\u003cp\u003eThis long shaft accessory is used in industrial and commercial electrical distribution applications where circuit breaker enclosures require extended shaft reach. It is specifically matched to work with the 9421LL1, LM1, LX7, or LW7 operating mechanism assemblies. Typical install scenarios include motor control centers, panelboards, and switchboard enclosures where the operator handle must bridge a physical gap between the door and the internal breaker mechanism.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLong shaft configuration extends handle reach for enclosed or offset mounting situations\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct accessory for 9421LL1, LM1, LX7, and LW7 operating mechanisms\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 2.8 inches height and 5.6 inches width for tight enclosure fitment\u003c\/li\u003e\n  \u003cli\u003e19.4 inch shaft length accommodates extended-reach installation requirements\u003c\/li\u003e\n  \u003cli\u003eSold as a single-unit package suitable for one operating mechanism assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the 9421LL1, LM1, LX7, or LW7 SQUARE D operating mechanism assemblies as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with NFPA 70 (NEC) requirements. De-energize and lock out the circuit before servicing any circuit breaker enclosure or operating mechanism assembly. Verify shaft alignment with the target operating mechanism before securing the assembly. Do not force or modify the shaft to fit non-compatible mechanism configurations.\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\u003eShaft Length\u003c\/strong\u003e: 19.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.05 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: 9421LS10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541534966066,"sku":"9421LS10","price":65.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df274bd6bc0a60fcb2e5a210d31230d8_707aa4a0-c4a5-444d-9ebe-32fb5e945012.jpg?v=1785878673","url":"https:\/\/voomisupply.com\/products\/square-d-9421ls10-circuit-breaker-operating-mechanism-long-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
