Panel Compatibility

The Square D BDA161251 is a 1-pole, 125A, 347/600V plug-in circuit breaker from the Square D BDA (I-Line) frame series. The BDA frame is an I-Line style breaker designed for use in Square D I-Line panelboards and switchboards — it is not a residential QO or Homeline loadcentre breaker. With a 14kA interrupting rating at 347/600V, it is suited to commercial and industrial distribution systems operating on Canadian 600V-class services.

Specific panelboard compatibility depends on the cubicle/section rating and bus configuration of your enclosure. Send us your panelboard model number and we'll confirm fit before you order.

The BDA161251 uses Square D's I-Line plug-in interface, so it is designed for Square D I-Line panelboards and switchboards rated for 347/600V operation — not residential QO or Homeline loadcentres. Because compatibility also depends on the specific panel's bus rating and breaker space dimensions, we recommend confirming with your panelboard model number. Contact our counter team in Calgary, Edmonton, or Vancouver and we'll verify fit for you.

The BDA frame series is an older Square D I-Line product line. Availability can be limited and varies between new, surplus, and reconditioned stock. Northern Breaker Group specialises in hard-to-find and obsolete breakers — reach out for a quote and we'll advise on what condition of stock is available and any relevant considerations for your application.

No — the BDA161251 is rated 347/600V and is intended for commercial or industrial 600V-class distribution systems common in Canadian facilities. It is not suitable for use in a standard residential 120/240V loadcentre. For residential applications, Square D QO or Homeline breakers would be the appropriate product family.
