UQFB-150 - 150Amp Circuit Breaker

UQFB-150 - 150Amp Circuit Breaker

If you’re working on a residential service setup and need a breaker that just does its job without headaches, the UQFB-150 is a solid pick. This 150 amp, 2-pole breaker is built for main cable-in/cable-out applications, making it a practical choice for homes where reliability and straightforward installation matter. It uses a thermal magnetic trip mechanism, which means it reacts appropriately whether you're dealing with a slow overload or a sudden short circuit. That kind of protection is what keeps panels, wiring, and connected equipment from taking a hit. With a 10kA interrupting rating at 120/240VAC, it’s well-suited for typical residential fault levels. Another thing worth noting—this breaker keeps a relatively compact profile. That can make a difference when you’re working inside a panel that doesn’t leave much room to spare. It’s designed to fit and function without forcing you to fight the install.
