No — the FA12030C is an I-Line frame breaker and is not compatible with QO or Homeline residential loadcentres. It is designed for Square D I-Line panelboards used in commercial and light industrial applications. If you need a residential plug-in breaker, you'll want a QO- or HOM-series breaker instead. Contact our team and we'll point you in the right direction.
The 'C' suffix on Square D FA-frame breakers denotes the breaker's trip curve characteristic — in this case, a standard thermal-magnetic trip. This is important when replacing an existing breaker, as the suffix must match your original unit to maintain proper overcurrent coordination. If you're unsure which variant you need, share your existing breaker details or panel specs with us and we'll help confirm.
Square D FA-frame breakers are considered a legacy/obsolete product line in many configurations. Northern Breaker Group specializes in hard-to-find and obsolete breakers — we maintain stock of and actively source FA-series units for exactly this reason. Reach out to our Calgary, Edmonton, or Vancouver counter for current availability and to request a quote.
