The Square D BDA360670 is a 3-pole, 70A, 600Y/347V, 14kA molded-case circuit breaker in Square D's BDA frame (I-Line plug-in) configuration.

- Mount type: I-Line plug-in (requires a compatible Square D I-Line panelboard or switchboard bus)
- Voltage: 600Y/347V — appropriate for Canadian 3-phase wye distribution
- Interrupting rating: 14kA symmetrical at 600V

The BDA frame uses Square D's I-Line plug-in bus system. Compatible enclosures include Square D I-Line panelboards and switchboards equipped with an I-Line bus — such as NF, PH, and similar Square D I-Line series. It is not interchangeable with QO, Homeline, or bolt-on panels. Contact our team with your panel model and we'll verify the fit.
Yes. The 600Y/347V voltage rating is specifically designed for Canadian commercial and industrial three-phase wye distribution — the standard found in most Canadian commercial buildings. The 347V phase-to-neutral voltage accommodates Canadian 347V lighting circuits, making this breaker well-suited for Canadian installations.
