It protects three‑phase branch circuits in compatible panelboards, delivering reliable overload and short-circuit protection in commercial or light‑industrial electrical distributions that require a bolted QOB device. The QOB380 designation identifies this exact model within the QOB lineup, ensuring compatibility with load centers that accept QOB/QO bolt-on breakers.
