Q221200AC - 200 Amp Circuit Breaker

Q221200AC - 200 Amp Circuit Breaker

If you're trying to match a Q221200AC circuit breaker already used in an electrical system, the details are what matter. This 200A, 2-pole Q2 molded-case circuit breaker is rated 10kA I.C. at 120/240VAC and uses thermal-magnetic trip protection. It has a Q-Frame design with I-Line plug-on mounting and A-C phasing, making it suitable for equipment designed for this specific configuration. The breaker measures 7.88 inches high, 3 inches wide, and 4.31 inches deep. For maintenance and replacement work on older electrical equipment, matching the breaker's frame, phasing, mounting method, amperage, voltage, and pole count can be just as important as matching the part number. The Q221200AC is built to last and provides a practical form, fit, and functional replacement when these specifications match the requirements of the existing system.

Key Features and Benefits

• 200-amp rating for compatible applications that require a 200-amp breaker.
