The QGA32090 Square D 3P 90A 240V I-Line Breaker is engineered for superior performance and reliability. This three-pole circuit breaker provides optimal protection for your electrical system, ensuring safety in commercial and residential applications. Built for the I-Line panel series, it offers easy installation and a robust design for long-lasting usage.
I-Line breakers like the QGA32090 use Square D's I-Line bus system, where the breaker plugs directly onto the bus bar with a proprietary stab connection rather than being bolted on. This makes installation and replacement faster, but it also means the QGA32090 is only compatible with Square D I-Line panelboards and switchboards — it cannot be used in standard bolt-on or QO-style loadcentres. Always verify your enclosure is an I-Line-rated panel before ordering.
Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain stock of legacy Square D I-Line devices including the QGA frame series. If the QGA32090 is not immediately available, our team can identify current Square D equivalents or compatible replacements that meet the same 90A, 3P, 240V, 65kA specifications. Contact us or request a quote and we'll source the best option for your application.
Yes — Square D QGA-frame I-Line breakers are approved for use in Canada and are commonly found in Canadian commercial and light-industrial installations. For compliance with the Canadian Electrical Code (CEC), ensure the breaker's 65kA interrupting rating meets or exceeds the available fault current at the point of installation, and that the panelboard it's installed in is also CSA-certified. If you have specific CEC compliance questions, we recommend consulting a licensed electrical contractor or your local authority having jurisdiction (AHJ).
