As part of the trusted Square D QO family, this breaker combines precise overcurrent protection with straightforward installation in compatible load centers. Part Number QO150HID.\u003c\/p\u003e \u003cp\u003eWhat makes this breaker stand out is its 50-amp rating in a compact 1-pole form, making it ideal for high-demand branch circuits, dedicated appliances, or motor loads in residential or light commercial settings. The 240-volt rating ensures it can safely interrupt and protect circuits that operate at higher voltage, while the single-pole design keeps panel layouts tidy and serviceable.\u003c\/p\u003e \u003ch3\u003eKey use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eProtect heavy-load 240V circuits such as large air conditioners, electric water heaters, or air handling equipment in homes or small businesses.\u003c\/li\u003e \u003cli\u003eIntegrate into metering or monitoring configurations that use a potential transformer for voltage sensing and energy management.\u003c\/li\u003e \u003cli\u003eReplace aging breakers in Square D QO panels with a proven, compatible replacement that maintains panel integrity.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy choose the QO150HID?\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility with Square D QO load centers\u003c\/strong\u003e ensures reliable operation and easy replacements.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e50 A current rating\u003c\/strong\u003e supports substantial branch circuits without unnecessary nuisance tripping for balanced loads.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e1-pole, 240 V configuration\u003c\/strong\u003e keeps wiring simple and minimizes space usage in the panel.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number QO150HID\u003c\/strong\u003e provides a precise match for replacement or upgrade projects focused on metering or transformer-based systems.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003ePractical tips: Verify your panel accepts QO-series breakers and that a 1-pole 240V device is appropriate for your circuit. When pairing with a potential transformer-based monitoring setup, ensure the breaker sits correctly in the bus and that the load does not exceed the 50 A rating. For installation, follow the panel's manual, align the breaker with the bus, and secure the toggle firmly to ensure proper tripping and engagement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Square D","offers":[{"title":"Default Title","offer_id":46423150493858,"sku":"QO150HID","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_229276d9-908d-46df-93e5-6fe31866e0ff.png?v=1765492975","url":"https:\/\/www.ampstate.com\/products\/square-d-qo150hid","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
