This component serves as the operator interface element mounted to a control enclosure, allowing technicians to initiate or interrupt electrical control circuits. The actuator is part of the SIEMENS 3SB3 series of modular pushbutton and indicator assemblies, which are widely used in machine control, motor starting, and industrial automation panels. Licensed electricians and industrial control panel builders are the primary installers of this type of component.\u003c\/p\u003e\n\u003cp\u003eThe 3SB3101-8DC21 is suited for installation in control enclosures across light industrial and commercial applications. It is typically paired with compatible contact blocks or base units within the 3SB3 modular system to complete the full switching assembly. This actuator fits standard 22-millimeter cutout mounting configurations common in NEMA and IEC-rated control panels used in manufacturing, HVAC mechanical rooms, pump control stations, and similar environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eModular 3SB3 series design compatible with standard 22-millimeter panel cutouts\u003c\/li\u003e\n  \u003cli\u003eActuator-only component allows flexible assembly with contact blocks and legend plates\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for dense control panel layouts\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at approximately 0.062 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation actuator for use within the SIEMENS 3SB3 modular pushbutton system. No additional specific compatible model numbers were provided in the product data.\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 applicable local codes. De-energize and lock out the control panel before removing or installing any pushbutton components. The actuator mounts into the panel cutout and secures to the base unit before contact blocks are attached — verify the full assembly is complete and properly seated before restoring power. Do not apply excessive force when snapping the actuator into the base, as this can damage the modular retaining clips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.062 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.953 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.654 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.520 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 75455451044\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: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3SB3101-8DC21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383449518386,"sku":"3SB3101-8DC21","price":88.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675295.jpg?v=1782596983","url":"https:\/\/voomisupply.com\/products\/siemens-3sb3101-8dc21-pushbutton-actuator","provider":"Voomi Supply","version":"1.0","type":"link"}
