QBA32125 - 125 Amp Circuit Breaker

QBA32125 - 125 Amp Circuit Breaker

The QBA32125 is a 125-amp, 3-pole Q-Frame circuit breaker designed for use with compatible I-Line electrical distribution equipment. It uses a plug-on connection and a thermal-magnetic trip mechanism, providing protection against overloads and short-circuit conditions. The breaker carries an interrupting rating of 10k AIC at 240VAC and measures approximately 7.88 inches high, 4.5 inches wide, and 4.31 inches deep. If you're replacing an existing breaker, those details matter. Amperage alone doesn't determine whether a breaker is the right fit; the frame, pole configuration, connection style, interrupting rating, and physical size all need to line up with the equipment. For applications requiring a QBA32125 Q-Frame, 125A, 3-pole I-Line plug-on breaker, this unit provides the required configuration without unnecessary complexity.

Material Compliance and Certifications

• No specific material compliance, certification, agency listing, or certification file information was included with the specifications provided for the QBA32125. If your job requires a specific approval or compliance standard, check the breaker label and the applicable product documentation before installation, rather than assuming certification based on the model number.

Where It Works Best

• The QBA32125 circuit breaker is a good fit for commercial and industrial electrical distribution applications that call for a 125A, 3-pole Q-Frame breaker with an I-Line plug-on connection. It's also well suited to maintenance and replacement work where an existing installation requires the same QBA configuration and electrical ratings.
