QBA220704 - 70 Amp Circuit Breaker Description
QBA220704 - 70 Amp Circuit Breaker
The QBA220704 PowerPact Q circuit breaker is built for one job—protecting your electrical system without getting in the way. Rated at 70 amps with a 2-pole configuration, it’s a dependable option for 240V distribution setups in commercial and light industrial environments. This breaker uses a thermal-magnetic trip, which gives you a good balance: it responds fast when there’s a fault, but doesn’t trip unnecessarily during normal operation. That’s exactly what you want in the real world—protection without constant interruptions. Installation is straightforward thanks to the I-Line connection on the line side, 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, so testing the breaker takes seconds instead of guesswork. If you’ve worked with PowerPact breakers before, you already know the appeal—they’re consistent, easy to work with, and built to last. This model follows that same formula.
