QDA221504 - 150 Amp Circuit Breaker Description
QDA221504 - 150 Amp Circuit Breaker
The QDA221504 PowerPacT Q circuit breaker is built for straightforward 240V applications where you need solid protection without overthinking the install. Rated at 150 amps with a 2-pole design, it handles everyday commercial and industrial loads while protecting against both overloads and short circuits using a thermal-magnetic trip system. With a 25kA interrupting rating, it’s equipped to deal with fault conditions you’ll actually see in the field. The I-Line connection on the line side makes it a good fit for compatible panelboards, helping speed up installation, while the load-side lugs keep wiring flexible. There’s also a push-to-trip button on the front—simple, but useful when you need to test the breaker without any extra steps. It’s the kind of breaker you install and don’t have to think about again.
