The BKA36030 SQUARE D 3P 30A 600Y/347V 65KA I LINE circuit breaker offers reliable protection for your electrical system. Designed for three-phase applications, it supports a maximum current of 30A and operates at 600Y/347V. With a remarkable interrupting capacity of 65KA, it ensures safety and efficiency in your installations.
Square D's I-Line system uses a plug-in bus connection where the breaker clips directly onto the I-Line bus stabs in compatible panelboards and switchboards, eliminating the need for individual bolted line-side lugs. This allows for faster installation and replacement compared to bolt-on MCCBs, but it means the BKA36030 will only seat correctly in Square D I-Line rated enclosures — it cannot be used in bolt-on or QO-style panels.
Yes — the BKA36030 is rated specifically for 600Y/347 V, which is the standard three-phase wye voltage used in Canadian commercial and industrial buildings. Its 65 kA interrupting capacity makes it appropriate for higher-fault-current environments such as main distribution panels and sub-feeds close to utility transformers. Always verify the available fault current at the point of installation against the 65 kA rating.
