Its fast plug-in connection means quick installation and easy replacement, minimizing downtime during service or upgrades.\u003c\/p\u003e \u003cp\u003eAt the heart of its performance is a thermal-magnetic trip unit: the magnetic element responds to immediate overcurrents, while the thermal element moderates nuisance trips from daily load variations. The result is stable, repeatable protection you can rely on for years.\u003c\/p\u003e \u003cp\u003eDesigned to align with matching OEM load centers and panelboards, the QO2175 offers a clean fit, simplified wiring, and coordinated protection across your electrical system. This makes it suitable for residential, commercial, and light industrial applications where robust 2-pole protection is needed.\u003c\/p\u003e \u003ch2\u003eTechnical snapshot\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Square D\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e QO2175\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Thermal-magnetic molded case circuit breaker\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage rating:\u003c\/strong\u003e 175 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 120 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNumber of poles:\u003c\/strong\u003e 2\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMounting style:\u003c\/strong\u003e Plug-in\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWhy this breaker is a smart choice\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eFast plug-in connection enables rapid installation and replacement, reducing panel downtime.\u003c\/li\u003e \u003cli\u003eThermal-magnetic trip unit delivers precise, repeatable protection under varying load conditions.\u003c\/li\u003e \u003cli\u003eOEM-compatible with matching load centers and panelboards for a seamless, code-compliant setup.\u003c\/li\u003e \u003cli\u003e2-pole design provides balanced protection for two conductors in residential, commercial, or light industrial applications.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePractical use scenarios\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eUpgrading a main service panel or subpanel that requires a 2-pole 175A breaker to protect feeders and branch circuits.\u003c\/li\u003e \u003cli\u003eReplacing an aging plug-in breaker in panelboards and load centers within the Square D QO family.\u003c\/li\u003e \u003cli\u003eProtecting heavy appliance or equipment circuits in light commercial environments, where reliable short-circuit protection is critical.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eFor best performance, pair the QO2175 with compatible Square D load centers and panelboards to ensure proper trip coordination and reliable long-term protection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46355399671970,"sku":null,"price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/square-d-qo2175-175-a-120-v-2-pole-plug-in-circuit-breaker-ampstate-414.webp?v=1788754555","url":"https:\/\/www.ampstate.com\/products\/square-d-qo2175-175a-120v-2-pole-plug-in-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
