UQFB-100 - 100Amp Circuit Breaker Description

UQFB-100 - 100 Amp Main Breaker

If you need a dependable main breaker for a residential setup, the UQFB-100 is a straightforward, get-the-job-done solution. Built as a cable-in/cable-out main breaker, this unit is designed to handle everyday electrical demands while protecting your system from overloads and short circuits. At 100 amps with a 2-pole configuration, it fits right into standard 120/240V residential applications. The thermal magnetic trip mechanism reacts quickly when something goes wrong—helping prevent damage before it turns into a bigger (and more expensive) problem. This breaker uses the UQFB frame, making it a solid match for compatible panels where a reliable main disconnect is needed. It’s compact, easy to work with, and built for consistent performance over time.
