QOB330GFI - 30Amp GFCI Circuit Breaker

QOB330GFI - 30Amp GFCI Circuit Breaker

When you’re dealing with an existing panelboard, the goal is simple—find a breaker that fits right and works the way it should. The QOB330GFI bolt-on circuit breaker is built with that in mind. It’s designed to match compatible systems without modification, making it a solid choice for replacements or ongoing maintenance. This 3-pole, 30-amp breaker includes built-in ground fault protection (GFI), helping shut off power when a fault is detected. That added layer of protection is especially important in commercial and industrial setups where safety and code compliance matter. The bolt-on design keeps the breaker firmly in place, which helps maintain a consistent electrical connection over time. It’s not complicated—and that’s the point. You get a breaker that lines up with your panel, installs securely, and does exactly what it’s supposed to do.
