QGA221751 - 175 Amp Circuit Breaker

QGA221751 - 175 Amp Circuit Breaker

When you’re dealing with a busy electrical system, the last thing you want is a breaker that can’t keep up. The QGA221751 PowerPacT Q circuit breaker is built for exactly those situations—where reliability isn’t optional. This 175 amp, 2-pole breaker is commonly used in 240VAC distribution setups, and it does what you expect without overcomplicating things. The thermal-magnetic trip unit handles both overloads and short circuits, reacting quickly to help protect your equipment and keep things running the way they should. It also checks the boxes that matter in the field. The 65kA interrupting rating means it’s ready for higher fault conditions, and the I-Line connection on the line side helps speed up installation in the right panelboards. On top of that, there’s a push-to-trip button, which makes testing simple—no extra steps or guesswork. If you’ve installed PowerPacT breakers before, you already know what to expect here. It’s a straightforward, dependable option that gets the job done without surprises.
