Designed for robust power distribution, the QGA222004 is a 200A, 2-pole molded case circuit breaker from the Square D PowerPacT Q-Frame series. It operates at 240VAC with a BC phase connection and provides a 65kAIC rating. This unit installs into Square D I-Line panelboards, including HCN, HCM, and HCW series, as well as switchboards. It serves as an exact replacement for the discontinued Q22200 model. Utilizing fixed thermal-magnetic trip technology, it ensures precise LI protection.
