QBA222252 - 225 Amp Circuit Breaker

QBA222252 - 225 Amp Circuit Breaker

When you’re dealing with a 240V system, the last thing you want is to second-guess whether a breaker will fit or perform the way it should. The QBA222252 PowerPacT Q circuit breaker is built for exactly that kind of situation—straightforward installation, solid protection, and compatibility with existing I-Line panelboards. This is a 225 amp, 2-pole breaker with a thermal-magnetic trip unit, which means it responds to both sustained overloads and sudden faults. It’s the kind of protection you expect in commercial and industrial distribution setups without adding unnecessary complexity. The I-Line connection on the line side helps it seat properly in the panel, while the mechanical lugs on the load side keep wiring simple and secure. There’s also a push-to-trip button right on the front. It’s a small detail, but it makes routine testing quick and easy—especially useful during maintenance checks. With a 10kA interrupting rating at 240VAC, this breaker is suited for standard applications where dependable fault interruption is required. If you’re replacing an existing unit or working within a PowerPacT Q setup, this model is designed to match the form and function you need—no guesswork, no modifications.
