QOB315 **Older Style** 15A Circuit Breaker

QOB315 **Older Style** 15A Circuit Breaker

If you're replacing a breaker in a compatible Type QOB panelboard, the QOB315 Older Style is built for that job. This 15-amp, 3-pole bolt-on circuit breaker is used in commercial and industrial electrical distribution systems where the original equipment calls for a Type QOB breaker. With a 10 kA interrupting rating at 240 VAC, it is intended for applications that meet these electrical requirements. The bolt-on mounting style helps create a secure connection inside the panel, while the three-pole design makes it suitable for protecting three-phase branch circuits. Whether you're performing routine maintenance, replacing a damaged breaker, or keeping an older electrical system in service, the QOB315 provides the correct form, fit, and function for compatible installations. It's built to last and intended to keep existing systems operating as originally designed.
