Q232125H - 125 Amp Circuit Breaker

Q232125H - 125 Amp Circuit Breaker

When you're maintaining an existing electrical system, finding a breaker that matches the original form, fit, and electrical ratings matters. The Q232125H circuit breaker is a 125-amp, 3-pole, Q-Frame molded case circuit breaker designed for compatible I-Line plug-on applications. This Type Q2H breaker features a thermal-magnetic trip mechanism and carries an A.I.C. rating of 22 kA at 240 VAC. Measuring approximately 7.88 inches high, 4.5 inches wide, and 4.31 inches deep, the Q232125H is a practical choice for maintaining compatible legacy electrical equipment that requires this specific breaker configuration. Rather than guessing whether a breaker will fit your application, you can compare the key details that matter: Q2H type, Q-Frame construction, 125A rating, three poles, I-Line plug-on connection, dimensions, and interrupting rating. When those specifications match the requirements of your existing equipment, the Q232125H provides the familiar configuration needed for a form, fit, and functional replacement. Simply put, it's built to last and designed to do the job specified for compatible Q-Frame I-Line systems.

Key Features and Benefits

• Designed for applications requiring a 125-amp three-pole circuit breaker with matching electrical characteristics.
• Helps simplify identification when you need to match an existing Q-Frame breaker instead of changing equipment configurations.
• Designed to connect with compatible I-Line electrical distribution equipment using the specified plug-on arrangement.
• Provides overload and short-circuit protection through a familiar thermal-magnetic trip mechanism.
• A clearly defined interrupting capacity makes it easier to confirm whether the breaker meets the requirements of the intended application.
• At 7.88" H x 4.5" W x 4.31" D, the physical dimensions can be checked against existing equipment before installation.
• Particularly useful when maintaining electrical systems where preserving the original breaker style, ratings, and connection method is important.
• Molded case construction is designed for dependable service when the breaker is properly selected, installed, and maintained within its specified ratings.

Material Compliance and Certifications

• Because electrical equipment must be carefully matched to its intended application, certification, listing, and material compliance information should always be verified for the specific Q232125H breaker being installed. The specifications provided here do not specify individual UL, CSA, RoHS, or other certification or material compliance details, so no additional certifications should be assumed.
• For installation, verify the product labeling and applicable equipment documentation to confirm that the breaker meets the electrical ratings, code requirements, and approvals required for the specific system. Installation and inspection should be performed by qualified electrical personnel in accordance with applicable electrical codes and safety requirements.

Where It Works Best

• The Q232125H Q2H circuit breaker is best suited for compatible I-Line electrical distribution equipment that specifically requires a Q-Frame, 125A, 3-pole, plug-on molded-case circuit breaker with a 22 kA interrupting rating at 240 VAC.
• It can be particularly useful when maintaining legacy electrical systems, existing panelboard installations, commercial electrical equipment, and other compatible distribution applications where matching the original breaker configuration is the priority. If you already have a Q232125H in service and need to maintain the same form, fit, and function, checking the part number is only the beginning. Confirm the frame, amperage, number of poles, voltage, and A.I.C. rating, I-Line connection, trip type, and physical dimensions as well.
