Q221200BC - 200 Amp Circuit Breaker

Q221200BC - 200 Amp Circuit Breaker

If you're replacing a Q221200BC circuit breaker, the details matter. This 200-amp, 2-pole Q2 molded-case circuit breaker is designed for compatible Q-Frame and I-Line plug-on applications and has B-C phasing. It uses a thermal-magnetic trip design and carries a 10 kAIC rating at 120/240 VAC. The breaker measures 7.88 inches high, 3 inches wide, and 4.31 inches deep. For older electrical equipment, those dimensions and connection details can be just as important as the amp rating. The Q221200BC is a good fit for maintenance situations where the existing system calls for this particular breaker configuration, and you want to keep the original form, fit, and function. It's a straightforward solution for the application it was designed to serve, with a molded-case construction built to last.

Key Features and Benefits

• 200-amp, 2-pole configuration for compatible 120/240VAC applications.
• 10k AIC rating at 120/240VAC.
• Thermal-magnetic trip design provides overload and short-circuit protection.
• B-C phasing for equipment requiring this specific phase arrangement.
• Q-Frame, Type Q2 design helps provide the correct physical fit in compatible equipment.
• I-Line plug-on connection for installations designed around this mounting style.
• Molded case construction protects the internal breaker components.
• Well-suited to legacy electrical system maintenance, where matching the existing breaker configuration is important.

Material Compliance and Certifications

• Certification, listing, and material-compliance information should be confirmed from the markings or documentation supplied with the individual Q221200BC breaker. No additional compliance or certification claims are being made beyond the specifications listed above.
• For installations subject to electrical codes or other regulatory requirements, confirm the breaker's markings, ratings, and suitability for the specific equipment before installation.

Where It Works Best

• The Q221200BC is best suited to existing electrical systems that require a 200A, 2-pole Q2 breaker with a Q-Frame, B-C phasing, and I-Line plug-on connection. It's particularly relevant for repair and maintenance work on legacy equipment, where changing the breaker style or configuration isn't the goal—the goal is to find the right match for the equipment already in place.
