The Square D BGA160203 is a 1-pole, 20A, 347/600V plug-in circuit breaker from Square D's BGA frame series, rated for 18kA interrupting capacity. The BGA frame is a commercial/industrial-grade breaker designed for use in Square D panelboards and loadcentres rated for 347/600V systems — common in Canadian commercial and light-industrial applications. It is not intended for standard 120/240V residential loadcentres.

  • Designed for Square D 347/600V panelboards accepting BGA-series plug-in breakers
  • Suitable for single-phase branch circuit protection in commercial and light-industrial installations

Send us your panelboard model and we'll confirm fitment — our team specialises in matching hard-to-find breakers to the right enclosures.

The BGA160203 is rated for 347/600V — the standard voltage system used in Canadian commercial and industrial buildings. Its 1-pole, 20A rating makes it ideal for single-phase branch circuit protection on 347V-to-neutral circuits, and its 18kA interrupting capacity meets the fault-current requirements of most commercial panelboards.

The Square D BGA frame series is considered a legacy/obsolete line, and new stock can be difficult to source through standard channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers — contact us and we'll check current inventory or identify a compatible Square D replacement for your application.

No. The BGA160203 is a commercial/industrial-grade 347/600V breaker and is not compatible with Square D QO or Homeline residential loadcentres, which are designed for 120/240V systems. It requires a Square D panelboard rated for 347/600V operation that accepts BGA plug-in breakers. If you're unsure, send us your panel details and we'll advise.
