QDA221502 - 150 Amp Circuit Breaker

QDA221502 - 150 Amp Circuit Breaker

When you’re protecting critical electrical systems, you don’t want to second-guess your equipment. The QDA221502 PowerPact Q circuit breaker is built for exactly that kind of confidence. Designed for 240VAC distribution systems, this 150-amp, 2-pole breaker delivers reliable overcurrent protection while keeping installation and maintenance straightforward. What really stands out is how this breaker balances performance with practicality. Its thermal-magnetic trip mechanism reacts quickly to overloads and short circuits, helping prevent damage before it becomes costly downtime. And with a 25kA interrupting rating, it’s ready to handle high fault conditions in demanding commercial and industrial environments. Installation is just as smooth. The I-Line connection on the line side allows for quick, secure mounting in compatible panelboards, while the mechanical lugs on the load side keep wiring simple. Need to test it? The built-in push-to-trip button makes routine checks easy—no guesswork, no hassle. If you’re upgrading a panel or specifying parts for a new project, this breaker gives you dependable protection without overcomplicating the job.
