The QOB115GFI by Square D is a reliable 1-Pole, 15 Amp, 120V bolt-in GFCI breaker designed for optimal safety in your electrical systems. Featuring a 5mA ground fault protection, it safeguards against electrical faults, providing peace of mind for your hot tub and other applications. Ensure safety with this essential circuit breaker.
The QOB115GFI uses a bolt-on mounting style where the breaker is secured directly to the bus bar with a screw, while the QO115GFI uses Square D's plug-on design. These two styles are not interchangeable — the QOB is intended for bolt-on QO panelboards and loadcentres, whereas the QO plug-on fits standard QO loadcentres. Check your panel's bus type or contact us to confirm which version you need.
