QDA221501 - 150 Amp Circuit Breaker

QDA221501 - 150 Amp Circuit Breaker

If you’ve worked with commercial or industrial panels before, you know how important it is to have a circuit breaker you don’t have to second-guess. The QDA221501 PowerPacT Q from Schneider Electric is built for exactly that—solid, dependable protection for 240V systems without unnecessary complexity. This is a 150 amp, 2-pole breaker designed to handle everyday loads as well as unexpected faults. It uses a thermal-magnetic trip system, so it responds appropriately whether you're dealing with a slow overload or a sudden short circuit. With a 25kA interrupting rating, it’s capable of safely clearing high fault currents, which is critical in real-world applications where things don’t always go as planned. One thing electricians tend to appreciate is how straightforward it is to install. The I-Line connection on the line side makes it a good fit for compatible panelboards, helping speed up installs and reduce headaches. There’s also a push-to-trip button right on the front, which makes testing quick and simple during maintenance checks. It’s not flashy—but that’s the point. This is a breaker designed to do its job consistently, whether it’s in a busy commercial building or part of an industrial setup.
