The Square D BGA160403 is a plug-in, single-pole 40A 347/600V molded-case circuit breaker in the BGA frame. Rated for 18kA interrupting capacity, it is designed for use in commercial and industrial panelboards and switchboards that accept BGA-frame plug-in breakers — it is not a residential loadcentre breaker. Compatibility depends on the specific panelboard's bus configuration and frame acceptance; send us your panelboard model and we'll confirm fitment.

The BGA160403 is a BGA-frame plug-in breaker rated for commercial and industrial panelboards and switchboards — not residential loadcentres. Compatibility depends on whether your panelboard accepts BGA-frame plug-in devices. Contact our team with your panelboard model number and we'll confirm whether this breaker is the right fit.

The BGA160403 is designed for use on Canadian 347/600V distribution systems, which are standard in commercial and industrial buildings across Canada. The 347V single-phase rating corresponds to the phase-to-neutral voltage of a 600V three-phase system. It is not suitable for use on standard 120/240V residential panels.
