It provides overcurrent and short-circuit protection for branch circuits in residential and light commercial load centers. With a 10 kiloamp interrupting rating, the Q120 is built to safely interrupt fault currents typical of standard service panels. Licensed electricians and qualified service personnel install this breaker as part of new panel builds, circuit additions, or direct replacement of failed overcurrent protection devices. It carries UL 489 approval, confirming it meets recognized standards for molded-case circuit breakers.\u003c\/p\u003e\n\u003cp\u003eThe Q120 is designed for use in load centers that accept plug-in style breakers. It is well-suited for protecting 20-amp branch circuits serving outlets, appliances, and dedicated equipment circuits in residential construction and light commercial applications. The plug-in mounting style allows for straightforward installation into compatible panelboards without additional hardware. Where a failed or tripped breaker on a 20-amp, single-pole circuit needs replacement, the Q120 is a direct-fit solution for compatible load centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp continuous current rating for standard branch circuit protection\u003c\/li\u003e\n  \u003cli\u003e120-volt AC voltage rating suitable for single-pole residential and light commercial circuits\u003c\/li\u003e\n  \u003cli\u003e10 kiloamp interrupting rating for safe fault current interruption\u003c\/li\u003e\n  \u003cli\u003ePlug-in mounting for tool-free installation into compatible load centers\u003c\/li\u003e\n  \u003cli\u003eUL 489 listed, meeting established standards for molded-case circuit breakers\u003c\/li\u003e\n  \u003cli\u003eSingle-pole configuration for 120-volt branch circuit applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in load centers that accept plug-in style single-pole breakers.

Always de-energize the main service disconnect and verify the panel is de-energized with a calibrated voltage tester before handling any breaker or wiring. Seat the breaker firmly into the bus bar clip until it is fully engaged before securing any load wiring. Do not install this breaker in panels where the bus bar configuration is incompatible with the plug-in mounting style.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 10 kiloamps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Plug-In\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Load Center\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 12.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL 489\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: Q120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SQUARE D","offers":[{"title":"Default Title","offer_id":51284017021234,"sku":"Q120","price":18.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278280.jpg?v=1781066161","url":"https:\/\/voomisupply.com\/products\/square-d-q120-circuit-breaker-20-amp-single-pole","provider":"Voomi Supply","version":"1.0","type":"link"}
