The BGA36070 SQUARE D 3P 70A 600Y/347V 18KA I LINE circuit breaker offers exceptional protection and reliability for your electrical systems. Designed for three-phase applications, it features a 70A rating and can handle voltages up to 600Y/347V. With an interrupting capacity of 18KA, this breaker ensures safety in demanding environments.
The BGA36070 uses Square D's I-Line plug-in bus system, so it is designed for Square D I-Line panelboards and switchboards (such as NF, NQ, and similar I-Line-rated enclosures). It is not compatible with QO or Homeline residential loadcentres. Send us your panelboard model number and we'll confirm compatibility for your specific installation.
The 600Y/347V rating means the BGA36070 is rated for a wye-configured three-phase system with 600V line-to-line and 347V line-to-neutral — the standard commercial distribution voltage used widely across Canada. It is well suited for lighting panels and commercial distribution boards fed from a 600V wye transformer secondary.
The Square D BGA frame series is an older I-Line product line and certain ampere ratings can be difficult to source through standard supply channels.
