It provides overcurrent and short-circuit protection for branch circuits in commercial and residential electrical distribution panels. The bolt-on mount design secures the breaker directly to the bus bar, reducing the risk of vibration-related loosening common with plug-in styles. A pressure plate terminal connection accommodates 14 to 8 AWG copper conductors. Licensed electricians install this breaker as part of a panelboard replacement, circuit addition, or service upgrade. It carries UL listing and CSA certification and meets RoHS compliance requirements.\u003c\/p\u003e\n\u003cp\u003eThe QOB120HM is designed specifically for use with Square D NQOD panelboards, making it a direct-fit replacement in commercial light-duty distribution applications. Typical install scenarios include branch circuit protection for lighting, HVAC controls, and general-purpose receptacle circuits. The single-pole configuration handles 120-volt branch loads. Its compact form factor fits standard NQOD panel spaces without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp overcurrent rating with 120-volt AC operating voltage\u003c\/li\u003e\n  \u003cli\u003eBolt-on mount type for secure, vibration-resistant installation on the bus bar\u003c\/li\u003e\n  \u003cli\u003ePressure plate terminal accepts 14 to 8 AWG conductors\u003c\/li\u003e\n  \u003cli\u003eSingle-pole design for 120-volt branch circuit protection\u003c\/li\u003e\n  \u003cli\u003eUL Listed, CSA certified, and RoHS compliant\u003c\/li\u003e\n  \u003cli\u003eDirect replacement fit for Square D NQOD panelboards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Square D NQOD panelboards as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify absence of voltage with a meter before handling any breaker or bus bar connections. Confirm conductor wire gauge falls within the 14 to 8 AWG range before terminating at the pressure plate. Do not exceed the breaker's rated amperage when sizing the protected circuit.\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 AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 14-8 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Connection Type\u003c\/strong\u003e: Pressure Plate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bolt-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed, CSA Certified, RoHS Compliant\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: QOB120HM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542799352114,"sku":"QOB120HM","price":59.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36b1d1adbc7576fb7192707a68262bfc.jpg?v=1785907733","url":"https:\/\/voomisupply.com\/products\/square-d-qob120hm-1-pole-bolt-on-circuit-breaker-20a","provider":"Voomi Supply","version":"1.0","type":"link"}
