BGA161003 SQUARE D 1P 100A 347/600V B PH I LINE

The BGA161003 is a plug-in MCCB from Square D's BGA frame series, rated 347/600 V for commercial and industrial use. It is generally compatible with Square D NQ, NF, and I-Line panelboards designed to accept BGA-frame plug-in breakers at this voltage. It is not suitable for residential loadcentres. Send us your panel model and we'll confirm compatibility.

Yes — the BGA161003 is rated for 347/600 V, making it well-suited for Canadian commercial and industrial installations operating on 600 V (line-to-line) or 347 V (line-to-neutral) systems, such as those fed from a 347/600 V wye transformer. Always verify the breaker's interrupting rating (18 kA) meets the available fault current at the point of installation, per CSA and local code requirements.

Availability of specific BGA-frame breakers can vary — some models have been phased out or replaced by newer Square D equivalents.
