QGA221502 - 150 Amp Circuit Breaker

QGA221502 - 150 Amp Circuit Breaker

If you’re replacing or maintaining a 240V distribution setup, the QGA221502 PowerPacT Q circuit breaker is one of those parts that simply needs to match—and work. This 150 amp, 2-pole breaker is designed for everyday overcurrent protection, using a thermal-magnetic trip that reacts to both gradual overloads and sudden faults. It’s a straightforward solution for keeping circuits protected without introducing complications into your system. Installation is just as practical. The I-Line connection on the line side helps it seat quickly into the right panelboard, and the mechanical lugs on the load side keep wiring simple and secure. With a 65kA interrupting rating, it’s built to handle higher fault conditions often found in commercial and industrial environments. Whether you're swapping out a failed unit or keeping an older system in service, this breaker is made to line up with existing specifications and get the job done.
