It occupies a standard 1-inch space in compatible loadcenters and provides overcurrent and short-circuit protection for branch circuits. The Q120 is sold individually and is a commonly specified replacement breaker for licensed electricians servicing ITE and Siemens loadcenters. Its compact, 1-inch single-pole form factor makes it straightforward to install in existing panels without modification to adjacent breakers or bus connections.\u003c\/p\u003e\n\u003cp\u003eThis breaker is suited for standard 120-volt branch circuit applications including lighting circuits, receptacle circuits, and small appliance circuits in residential homes, multifamily buildings, and light commercial facilities. It fits directly into ITE and Siemens panelboards that accept the Q-line breaker form factor. Electricians typically specify this part during panel upgrades, breaker replacements, or new circuit additions where a 20-amp single-pole position is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp single-pole configuration for 120-volt branch circuits\u003c\/li\u003e\n  \u003cli\u003eStandard 1-inch panel space — installs without adjacent breaker displacement\u003c\/li\u003e\n  \u003cli\u003eCompatible with ITE and Siemens Q-line loadcenters\u003c\/li\u003e\n  \u003cli\u003eProvides overcurrent and short-circuit protection per NEC branch circuit requirements\u003c\/li\u003e\n  \u003cli\u003eSold individually (unit of measure: EA)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement single-pole breaker for ITE and Siemens Q-line panelboards accepting 1-inch single-pole positions.\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 any applicable local amendments. Always de-energize the panelboard at the utility disconnect and verify the bus is de-energized with a verified meter before handling breakers or bus connections. Confirm the panel accepts the Q-line breaker form factor before installation. Do not exceed the panel's maximum breaker count or total amperage rating when adding circuits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Space\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.73 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12\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 Industry Inc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: Q120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51524619469106,"sku":"Q120","price":126.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b29f3d8d7b535e274b7ffa00ad52d663.jpg?v=1785453255","url":"https:\/\/voomisupply.com\/products\/siemens-q120-20a-single-pole-circuit-breaker-120v","provider":"Voomi Supply","version":"1.0","type":"link"}
