It provides overcurrent and short-circuit protection in residential and light commercial electrical panels. The panel-mount design uses box lug terminals and accepts wire sizes ranging from 12 AWG to 2\/0 AWG, giving installers flexibility across a range of load conductor sizes. The QOU170 carries UL listing and CSA and IEC certifications, along with RoHS compliance. Licensed electricians install this breaker as part of load-center wiring for dedicated branch circuits serving high-draw equipment.\u003c\/p\u003e\u003cp\u003eThe QOU170 is rated for use with air conditioning and refrigeration equipment as well as heating systems. It is suited for dedicated branch circuits where a single-pole 70-amp protective device is required. The panel-mount form factor fits load centers designed to accept QOU-series breakers. This breaker is a practical choice for HVAC contractors and electricians wiring condensing units, heat strips, and similar high-amperage single-phase loads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e70-amp continuous rating at 240 volts AC for high-draw branch circuits\u003c\/li\u003e\n\u003cli\u003eSingle-pole configuration with panel-mount installation\u003c\/li\u003e\n\u003cli\u003eBox lug terminals accept 12 AWG through 2\/0 AWG conductors\u003c\/li\u003e\n\u003cli\u003eUL listed, CSA certified, IEC compliant, and RoHS compliant\u003c\/li\u003e\n\u003cli\u003eRated for air conditioning, refrigeration, and heating equipment applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with air conditioning and refrigeration equipment and heating systems.

De-energize the panel and verify the absence of voltage before handling any breaker or wiring. Confirm that the conductor size and type are appropriate for a 70-amp circuit before terminating at the box lugs. Do not exceed the wire size range of 12 AWG to 2\/0 AWG at the terminal connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 70 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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size Range\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: QOU170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542067249458,"sku":"QOU170","price":126.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83f19287dbdb86b48e8d0bc3a77bcdc7_fa8f9a10-edc3-4ecd-854f-df44c1631ccd.jpg?v=1785891087","url":"https:\/\/voomisupply.com\/products\/square-d-qou170-miniature-circuit-breaker-70a-1-pole","provider":"Voomi Supply","version":"1.0","type":"link"}
