QBA221752 - 175 Amp Circuit Breaker

QBA221752 - 175 Amp Circuit Breaker

The QBA221752 is a 175 amp, 2 pole molded case circuit breaker designed for use in 240VAC electrical distribution systems. Built on the PowerPact Q-Frame platform, this breaker uses a thermal magnetic trip mechanism to provide dependable protection against overloads and short circuits. With a 10kA interrupting rating at 240VAC, it is intended for applications where proper fault interruption and system coordination are essential.

This model features an I-Line, plug-on connection, allowing it to install directly into compatible panelboards and switchboards designed for Q-Frame breakers. If you are replacing an existing unit, the QBA221752 is designed to match the original form, fit, and function required for Q-Frame systems. Its molded case construction is built to last and suitable for demanding commercial and industrial environments.
