QGA221752 - 175 Amp Circuit Breaker

QGA221752 - 175 Amp Circuit Breaker

If you’re trying to match an existing breaker in an I-Line panel, the QGA221752 PowerPact Q is one of those straightforward, drop-in solutions that makes the job easier. No guesswork on fit, no adapting—just the right specs for the system you’re working on. This is a 175-amp, 2-pole breaker built for 240VAC applications, using a thermal-magnetic trip to handle both overloads and short circuits. It’s the kind of protection most systems were designed around, so it behaves the way you expect under normal conditions and fault events. On the install side, you’ve got an I-Line connection on the line side, which is exactly what you need for compatible panelboards, and mechanical lugs on the load side that accept a wide range of wire sizes. Nothing complicated here—just standard, practical connections that electricians deal with every day. One small but useful feature is the push-to-trip button on the front. It lets you manually trip the breaker during testing or maintenance without pulling anything apart. It’s simple, but it saves time when you’re verifying operation. Bottom line: this breaker is built to do its job and keep doing it. If you’re maintaining or replacing components in an existing setup, this is the kind of part that fits right in and keeps things moving.
