UQFB100-X-MOD - 100Amp Circuit Breaker

UQFB100-X-MOD - 100 Amp Circuit Breaker

When you’re dealing with your main breaker, you don’t want to overthink it—you just want something that works, fits right, and protects your system without issues. The UQFB100-X-MOD is built for exactly that. This is a 100 amp, 2-pole bolt-in breaker designed for residential panels. It handles standard 120/240V setups and gives you solid protection against overloads and short circuits. The thermal magnetic trip does what it’s supposed to—trips fast when there’s a fault, but doesn’t get in the way during normal use. Installation is straightforward if you’re working with a compatible panel. The bolt-in style keeps it firmly in place, which is what you want for a main breaker. No looseness, no guesswork. With a 10kA interrupting rating, it’s capable of safely stopping fault currents when something goes wrong. That’s the kind of behind-the-scenes reliability most people never notice—but absolutely need.
