Description
Built to manage substantial fault currents, this 125-amp high-interrupting molded case breaker provides 42kAIC protection for 240VAC commercial networks. The thermal-magnetic trip unit ensures precise response to both sustained overloads and sudden short circuits. Installation is streamlined for Siemens P1, P2, and P3 panelboards, utilizing a dependable bolt-on configuration. It serves as an exact physical match for older enclosures before transitioning to the newer HQR23B125 series.
