This handle attaches to the 9421LW7 operating mechanism and provides the external actuation point for opening and closing the circuit breaker without direct contact with internal components. Measuring 8.8 inches in length, 6.8 inches in width, and 4.5 inches in height, it is sized to integrate directly with the corresponding mechanism assembly. Licensed electricians and industrial maintenance technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis handle is suited for panel and enclosure applications where an external operating mechanism is required to actuate a circuit breaker through a door or panel surface. It is specified for use with the SQUARE D 9421LW7 operating mechanism, making it appropriate for replacement and maintenance work on existing installations that already incorporate that mechanism. Typical installations are found in commercial and industrial facilities where safety interlocks and door-operated breaker actuation are required by code or facility standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned as a direct replacement handle for the 9421LW7 operating mechanism assembly\u003c\/li\u003e\n  \u003cli\u003eExternal actuation allows breaker operation without opening the enclosure door\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of one handle per unit for straightforward single-unit replacement\u003c\/li\u003e\n  \u003cli\u003eDimensions of 8.8 x 6.8 x 4.5 inches provide a defined fit envelope for enclosure planning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the SQUARE D 9421LW7 operating mechanism.

De-energize and lock out the circuit before accessing any breaker or operating mechanism components. Verify that the handle model matches the specific operating mechanism installed in the enclosure before assembly. Do not force the handle into position; consult the mechanism documentation to confirm correct alignment and mounting procedure.\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\u003eFor Use With\u003c\/strong\u003e: 9421LW7 Operating Mechanism\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: 6.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.5 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: 9421LHP8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541959901490,"sku":"9421LHP8","price":127.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1aeba4cab7211655e6ef76ef8d396617.jpg?v=1785888474","url":"https:\/\/voomisupply.com\/products\/square-d-9421lhp8-circuit-breaker-operating-mechanism-handle","provider":"Voomi Supply","version":"1.0","type":"link"}
