BKA36035 SQUARE D 3P 30A 600Y/347V 65KA I LINE

The BKA and BK frames share the same I-Line plug-in footprint, but the BKA frame carries a higher interrupting rating (65kA vs. the standard BK's lower rating). They are physically compatible with the same Square D I-Line panelboards, but you should always verify that the panelboard's short-circuit current rating (SCCR) and bus rating match the breaker you install. Contact us or your Square D rep to confirm before substituting.

Yes — the 600Y/347V rating means this breaker is suitable for use on 347V line-to-neutral and 600V line-to-line conductors, which is the standard Canadian 347/600V wye distribution system. It is not rated for 600V delta (ungrounded) systems. Always confirm your system voltage and grounding configuration before installation.

Yes, Northern Breaker Group specialises in obsolete and hard-to-find breakers, including Square D BKA-frame units. We can source new-old-stock or professionally reconditioned breakers. Reconditioned MCCBs are tested and reset to manufacturer trip specifications; we recommend requesting documentation of the reconditioning process and confirming acceptability with your authority having jurisdiction (AHJ) prior to installation, as some jurisdictions have specific rules regarding reconditioned breakers.
