It provides overcurrent and short-circuit protection for branch circuits in residential and light commercial electrical systems. Box lug terminal connections accept wire sizes from 14 to 2 AWG, giving installers flexibility across a range of conductor sizes. The QOU245 carries UL Listed, CSA, IEC, and RoHS certifications, meeting the compliance requirements common to HVAC, refrigeration, and heating equipment branch circuits.\u003c\/p\u003e\n\u003cp\u003eThe QOU245 is suited for branch circuit protection serving air conditioning and refrigeration equipment as well as electric heating loads. It is a panel mount breaker intended for installation in compatible load center enclosures. Electricians and HVAC technicians commonly specify this breaker when protecting dedicated equipment circuits in both new construction and service replacement applications. The 2-pole configuration interrupts both ungrounded conductors simultaneously, as required for 240-volt branch circuits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-amp continuous rating with 240 VAC 2-pole overcurrent protection\u003c\/li\u003e\n  \u003cli\u003eBox lug terminal connections accept 14 to 2 AWG conductors\u003c\/li\u003e\n  \u003cli\u003ePanel mount design for load center installation\u003c\/li\u003e\n  \u003cli\u003eRated for air conditioning, refrigeration, and heating equipment circuits\u003c\/li\u003e\n  \u003cli\u003eUL Listed, CSA certified, IEC compliant, and RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with air conditioning and refrigeration equipment and heating systems as an OEM-style panel mount circuit breaker replacement.

De-energize the panel and verify the absence of voltage before handling or installing the breaker. Ensure wire terminations are seated fully in the box lug terminals and torqued per the terminal markings on the device. Do not install the breaker in a load center that does not accept the QOU series format.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 45 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 240 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 14 to 2 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Connection Type\u003c\/strong\u003e: Box Lugs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Panel Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Breaker Type\u003c\/strong\u003e: Miniature Circuit Breaker\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.79 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL Listed, CSA, IEC, 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: QOU245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541234712882,"sku":"QOU245","price":147.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1149d55eb85d79ec4ea7fc5584cb9698_3dad5494-e40d-48ef-bfd9-574d70920a6f.jpg?v=1785870487","url":"https:\/\/voomisupply.com\/products\/square-d-qou245-45a-240v-2-pole-miniature-circuit-breaker","provider":"Voomi Supply","version":"1.0","type":"link"}
