QGA221501 - 150 Amp Circuit Breaker Description
QGA221501 - 150 Amp Circuit Breaker
When you’re working with an existing 240VAC distribution setup, you don’t need guesswork—you need a breaker that fits right and performs as expected. The Schneider Electric QGA221501 PowerPacT Q circuit breaker is built for exactly that. Rated at 150 amps with a 2-pole design, it provides reliable overcurrent protection using a thermal-magnetic trip system that reacts to both overloads and short circuits. This model uses an I-Line connection on the line side and mechanical lugs on the load side, making it a straightforward match for compatible panelboards already in place. With a 65kA interrupting rating at both 208Y/120VAC and 240VAC, it’s suited for systems where fault current levels need to be handled without hesitation. There’s also a built-in push-to-trip button on the front—simple, but useful when you want to verify operation during maintenance without pulling the unit.
