QGA221754 - 175 Amp Circuit Breaker

QGA221754 - 175 Amp Circuit Breaker

When you're working with electrical distribution systems, you need components you don’t have to second-guess. The Schneider Electric QGA221754 PowerPacT Q circuit breaker is designed for exactly that—solid, consistent protection in everyday commercial and industrial applications. This 175 amp, 2-pole breaker is built for 240VAC systems and uses thermal-magnetic trip technology to handle both overloads and short circuits. It reacts quickly when something’s wrong, helping protect your equipment before damage spreads. With a 65kA interrupting rating, it’s well-suited for systems where higher fault currents are a concern. From an installation standpoint, it keeps things simple. The I-Line connection on the line side allows for quick, secure mounting, while the mechanical lugs on the load side give you flexibility in the field. There’s also a push-to-trip button right on the front, so testing the breaker is straightforward—no extra steps or tools needed.
