No. Square D I-Line breakers use a proprietary bus-stab and clip retention system that is unique to I-Line panelboards and switchboards. They are physically and electrically incompatible with QO loadcentres or any other Square D residential/commercial panel format. Always confirm your enclosure is rated for I-Line FA-frame devices before ordering.
Square D's FA-frame I-Line line has seen product transitions over the years, and certain configurations can be difficult to find through regular distribution channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers — contact our Calgary, Edmonton, or Vancouver counters or request a quote online and we'll locate new, surplus, or reconditioned stock for you.
The FA-frame series is commonly applied in commercial and industrial motor branch-circuit and feeder protection up to 600 V AC. Whether the 14 kA interrupting rating meets your local code requirements depends on the available fault current at the point of installation — your electrician or engineer should conduct a short-circuit study to confirm suitability under the Canadian Electrical Code (CEC).
