Q221225BC - 225 Amp Circuit Breaker

Q221225BC - 225 Amp Circuit Breaker

The Q221225BC is a 225-amp, 2-pole Q2 molded-case circuit breaker designed for compatible Q-Frame and I-Line plug-on applications. It uses thermal-magnetic protection, has 2 "B-C" phasing, and is rated at 10 kAIC at 120/240 VAC. If you're replacing a breaker in existing equipment, those details are important. Matching the amperage alone isn't enough; the frame, phasing, number of poles, voltage, interrupting rating, and mounting style must all suit the application. The Q221225BC measures 7.88 inches high, 3.0 inches wide, and 4.31 inches deep, providing another useful reference when checking an existing installation. For facilities and electrical systems that require this particular Q2 configuration, it provides the required form, fit, and function without altering the intended setup. Its molded case construction is also built to last when the breaker is properly installed and used within its specified ratings.

Key Features and Benefits

• 225 amp, 2-pole configuration for applications requiring these specific electrical characteristics.
• Q2 type and Q-Frame design help simplify identification when matching an existing breaker.
• 2 "B-C" phasing for systems specifically configured around this phasing arrangement.
• I-Line plug-on connection provides the mounting style required by compatible distribution equipment.
• Thermal-magnetic operation provides overcurrent protection in accordance with the breaker's design.
• 10k AIC at 120/240VAC clearly defines the breaker's interrupting and voltage ratings.
• Straightforward replacement option when an existing application requires the Q221225BC specifications.
• Built to last, with molded case construction intended for ongoing service when correctly applied and maintained.

Material Compliance and Certifications

• Specific material-compliance and certification information was not included in the available specifications for the Q221225BC, so no additional certifications or listings are claimed here. Requirements can vary by equipment and installation.
• Check the individual breaker label and applicable documentation before installation. The 225A rating, 2-pole configuration, 120/240VAC rating, 10k AIC, B-C phasing, Q-Frame design, and I-Line plug-on connection should all match the requirements of the equipment in which the breaker will be used.

Where It Works Best

• The Q221225BC circuit breaker makes the most sense for existing electrical distribution equipment designed around this particular Q2/Q-Frame configuration. It's especially useful for maintenance and replacement work where changing the original breaker arrangement isn't the goal—you simply need a breaker with the correct specifications for the existing system.
