QO315 **Older Style** 15A Circuit Breaker

QO315 **Older Style** 15A Circuit Breaker

If you're working on an existing Type QO panel, finding the correct breaker is just as important as matching the amp rating. The QO315 Older Style is a 3-pole, 15-amp plug-on circuit breaker built for use in compatible Type QO load centers and panelboards. With a 10kA interrupting rating at 240VAC, it provides branch circuit protection from overloads and short circuits while matching the form and fit of older-style QO installations.

Instead of changing panel components or trying to make a different breaker work, this model is intended for applications that require the original configuration. The plug-on connection allows it to install in compatible equipment without modification, making it a practical replacement during repairs, maintenance, or routine service. Like the original design, it's built to last and intended for dependable operation in compatible electrical systems.
