    Panel & Switchboard Compatibility

    The Square D BJA36100 is a 3-pole, 100 A, 600Y/347 V I-Line plug-in MCCB from the Square D BJ/BJA frame series, rated 25 kA interrupting capacity. As an I-Line plug-in device, it is designed to mount in Square D I-Line panelboards and switchboards — commercial and industrial enclosures that accept the I-Line bus system — rather than residential loadcentres.

    • Voltage: 600Y/347 V AC, suitable for Canadian 347/600 V wye distribution systems
    • Poles: 3-pole (note: the listing title references "1P" — please confirm your pole and frame requirements when ordering)
    • Mount: I-Line plug-in; not interchangeable with QO or Homeline loadcentres

    Send us your panelboard or switchboard model number and we'll confirm fit before you order.

    The BJA36100 uses Square D's I-Line plug-in mounting system, so it is designed for Square D I-Line panelboards and switchboards used in commercial and industrial installations. It is not compatible with residential QO or Homeline loadcentres. Share your panelboard model with us and we'll confirm compatibility.

    The BJA frame in the 36100 catalogue number typically denotes a 3-pole (3P) breaker at 600Y/347 V. The '1P' reference in the title appears to be a listing discrepancy. We recommend confirming the exact pole configuration you need when you request a quote — our team can verify the precise catalogue number and ensure you receive the correct unit.

    Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain stock of legacy Square D I-Line units including the BJA frame series. Availability can vary, so contact us or request a quote through our Calgary, Edmonton, or Vancouver counters and we'll check current inventory for you.
