UQFB-125 - 125A Circuit Breaker

UQFB-125 - 125A Circuit Breaker

If you’re replacing a main breaker or working on a residential panel that calls for a UQFB frame, the UQFB-125 is one of those parts you don’t have to overthink. It’s a 125 amp, 2-pole circuit breaker designed for standard 120/240V systems, and it does exactly what it’s supposed to do—protect your system without creating headaches. This breaker uses a thermal magnetic trip, which is what most residential setups rely on. In plain terms, it handles both slow overloads and sudden faults the way it should. No guesswork, no unnecessary tripping—just consistent performance. The 10kAIC rating gives you the interrupting capacity needed for typical residential applications, whether you’re installing new or swapping out an existing unit. And since it’s a cable-in/cable-out design, it fits right into the kind of setups electricians deal with every day.
