The BGA36100 is a Square D BGA-frame molded-case circuit breaker rated 100A, 3-pole, 600Y/347V, 18kA with an I-Line plug-in mounting.

It is not intended for residential loadcentres (QO or Homeline).

  • Mounting: I-Line plug-in (not bolt-on, not QO)
  • Voltage: 600Y/347V AC — suited to Canadian 347/600V wye distribution systems
  • Interrupting rating: 18kA symmetrical at 600V

Have a panelboard or switchboard to match? Send us your panel model and we'll confirm fit before you order.

The BGA36100 uses Square D's I-Line plug-in mounting, so it is compatible with Square D I-Line panelboards and switchboards designed to accept I-Line breakers. It is not interchangeable with QO, Homeline, or bolt-on style equipment. If you're unsure whether your panel accepts I-Line breakers, send us the panel model number and we'll confirm compatibility.

Yes. The 600Y/347V rating is the standard Canadian commercial and industrial wye distribution voltage, where 347V appears line-to-neutral and 600V line-to-line. This makes the BGA36100 well suited for lighting and power circuits in commercial buildings, multi-unit residential common areas, and industrial facilities fed from a 600V wye transformer. It is not rated for 120/240V single-phase residential service.
