The Square D BGA36090 is a 3-pole, 90A, 600Y/347V molded-case circuit breaker in the BGA frame, rated 18kA short-circuit current (SCC) with an I-Line plug-in mounting configuration. It is designed for commercial and industrial panelboards and switchboards that accept Square D I-Line plug-in breakers — not residential loadcentres. Typical applications include lighting panels, distribution boards, and branch-circuit protection in three-phase 347/600V systems common in Canadian commercial construction.
- Mounting: I-Line plug-in (compatible with Square D I-Line panelboards and switchboards)
- Voltage: 600Y/347V AC, 3-phase — suited to Canadian commercial voltage systems
- Interrupting Rating: 18kA at 600V
Compatibility depends on your specific panelboard's bus rating and I-Line configuration — send us your panel model and we'll confirm fitment.
The BGA36090 uses Square D's I-Line plug-in mounting, so it is designed for Square D I-Line panelboards and switchboards rated for I-Line breakers. It is not compatible with QO or Homeline loadcentres. Because compatibility also depends on your panel's bus rating and configuration, we recommend sending us your panel model number so we can confirm before you order.
Yes — the BGA36090 is rated 600Y/347V, which is the standard three-phase voltage system widely used in Canadian commercial and industrial facilities for lighting and power distribution. Its 3-pole design and 18kA interrupting rating make it well suited for branch-circuit and feeder protection in these applications.
The BGA frame I-Line series has seen product lifecycle changes over the years. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so whether the BGA36090 is a current or discontinued part, we can source it or identify a suitable authorized replacement.
