BGA36125 SQUARE D 3P 125A 600Y/347V 18KA I LINE
The BGA36125 Square D 3-Pole Circuit Breaker is designed for reliable performance in demanding conditions. With a 125A current rating and a voltage capacity of 600Y/347V, this breaker offers robust protection rated at 18kA. Ideal for commercial applications, it ensures safety and efficiency in your electrical systems.
The BGA36125 uses Square D's I-Line plug-in mounting system. It is compatible with Square D I-Line panelboards and switchboards designed for plug-in MCCBs — not residential QO or Homeline loadcentres. If you're unsure whether your panelboard accepts I-Line plug-in breakers, send us the panel model number and we'll verify compatibility.
Yes. The BGA36125 is rated 600Y/347 V, which is the standard three-phase, 4-wire voltage system widely used in Canadian commercial and institutional buildings. Its 18 kA interrupting capacity makes it appropriate for distribution panelboards in these applications. Always verify that the available fault current at your panel does not exceed 18 kA.
The BGA-frame I-Line series has seen limited availability as Square D transitions product lines. Northern Breaker Group specialises in obsolete and hard-to-find breakers and maintains stock of legacy Square D MCCBs. Contact our Calgary, Edmonton, or Vancouver counter or request a quote online — we'll advise on current availability or a suitable equivalent if needed.
