    Panel Compatibility

    The Square D BGA160451 is a 1-pole, 45A, 347/600V plug-in breaker from the BGA (BG-frame) series, rated at 18kA interrupting capacity. This frame is designed for commercial and industrial panelboards and loadcentres that accept Square D BG-frame plug-in breakers — it is not a residential QO or Homeline device. It is suited for 347/600V single-phase branch-circuit protection in multi-wire distribution systems commonly found in Canadian commercial installations.

    Compatibility depends on your specific panelboard's busbar configuration and plug-in acceptance. Send us your panel model and we'll confirm fitment.

    The BGA160451 belongs to Square D's BG-frame plug-in series, intended for commercial and industrial panelboards rated for 347/600V systems — not residential QO or Homeline loadcentres. The exact compatible panelboard models depend on busbar design and plug-in slot configuration. Contact our team with your panel model number and we'll confirm compatibility.

    Yes. The BGA160451 is rated at 347/600V, which aligns directly with Canada's standard commercial and industrial distribution voltage. Its 18kA interrupting rating makes it appropriate for branch-circuit protection in typical Canadian commercial panelboards where fault current levels are within that threshold.

    BG-frame Square D breakers can be difficult to source through standard supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain stock of legacy Square D commercial breakers.
