It accepts wire sizes from 12 AWG through 2\/0 AWG via box lug terminals, making it suitable for branch circuit protection on higher-draw loads. Licensed electricians install this breaker during new construction, service upgrades, or circuit replacements. It carries UL Listed, CSA, IEC, and RoHS compliance certifications, meeting the standards required for most North American and international installation scenarios.\u003c\/p\u003e\n\u003cp\u003eThe QOU290 is rated for use with air conditioning and refrigeration equipment as well as heating systems, making it a common choice for HVAC disconnect and branch circuit protection applications. Its panel mount configuration fits standard load centers that accept QOU-series breakers. The box lug terminal connection supports a wide conductor range, accommodating both smaller branch circuit wiring and larger feeder conductors up to 2\/0 AWG.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-amp continuous rating at 240 volts AC for high-draw branch circuit protection\u003c\/li\u003e\n  \u003cli\u003e2-pole configuration interrupts both ungrounded conductors simultaneously\u003c\/li\u003e\n  \u003cli\u003eBox lug terminals accept 12 AWG through 2\/0 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\u003eRated for use with air conditioning and refrigeration equipment and heating systems.

De-energize the panel and verify the absence of voltage with a meter before handling any breaker or bus connections. Ensure conductor size is within the rated 12 AWG to 2\/0 AWG range before terminating at the box lugs. Do not exceed the breaker's 90-amp continuous rating for the connected load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 90 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 240 volts AC\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: 12 to 2\/0 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\u003eHeight\u003c\/strong\u003e: 2.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.94 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: QOU290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542454370610,"sku":"QOU290","price":388.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1149d55eb85d79ec4ea7fc5584cb9698_e697996d-497c-4bc0-9d18-028471d8b630.jpg?v=1785900959","url":"https:\/\/voomisupply.com\/products\/square-d-qou290-90a-240v-2-pole-miniature-circuit-breaker","provider":"Voomi Supply","version":"1.0","type":"link"}
