The BJA36050 Square D 3P 50A 600Y/347V I-Line Circuit Breaker is designed for reliable protection in commercial and industrial applications. With a short-circuit current rating of 25kA, this three-pole breaker ensures safety and performance under demanding conditions. Ideal for your power distribution needs, it combines durability with efficiency.
The BJA36050 uses Square D's I-Line plug-in bus system, so it is compatible with Square D I-Line panelboards and switchboard sections designed for the I-Line breaker family. It is not interchangeable with QO or Homeline residential loadcentres. Because I-Line enclosures span many catalogue numbers, we recommend sharing your panelboard model with our team so we can confirm compatibility before you order.
Yes. The BJA36050 is specifically rated at 600Y/347 V, which matches the standard Canadian commercial and industrial distribution voltage (347 V phase-to-neutral, 600 V phase-to-phase). Its 25 kA short-circuit current rating (SCCR) must be verified against the available fault current at the installation point to ensure code compliance under the Canadian Electrical Code (CEC).
Square D has transitioned much of its I-Line MCCB lineup over the years, and availability of specific BJ-frame catalogue numbers can vary. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada, with counter locations in Calgary, Edmonton, and Vancouver.
