QGA32175 - 175 Amp Circuit Breaker

QGA32175 - 175 Amp Circuit Breaker

The QGA32175 is a 3-pole, 175-amp molded case circuit breaker built for protecting three-phase electrical distribution systems from overloads and short circuits. It uses a thermal magnetic trip unit, which responds to long-term overload conditions as well as sudden fault currents to help protect connected equipment.

This breaker is part of the Q-Frame family and features an I-Line plug-on mounting design, making it compatible with select panelboard applications where quick installation or replacement is important. With an interrupting rating of 65kA at 240VAC, it is suitable for installations where higher available fault current is present. Whether you're replacing an existing breaker during maintenance or completing a new installation, the QGA32175 provides the electrical protection expected in commercial and industrial power distribution systems.
