BGA160453 SQUARE D 1P 45A 347/600V B PH I LINE

The BGA160453 uses Square D's I-Line plug-in mounting system, which is compatible with Square D I-Line panelboards and switchboards designed for that bus style. These are industrial/commercial distribution boards — not residential QO or Homeline loadcentres. If you're unsure whether your board accepts I-Line plug-in devices, share your panelboard model number with us and we'll verify the fit.

Yes. The BGA160453 is rated for 347/600V, making it well suited for the 347V single-phase branch circuits (line-to-neutral on a 600V system) common in Canadian commercial and industrial buildings — used for lighting and general-purpose loads. Its 18kA interrupt rating meets the fault-current requirements of most commercial distribution systems at that voltage.

Square D's BGA I-Line series breakers can be difficult to source as stock levels vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers across Canada, with counters in Calgary, Edmonton, and Vancouver. Whether the BGA160453 is a current or discontinued part, contact us for a quote and we'll do our best to locate it for you.
