Q221225AB - 225 Amp Circuit Breaker

Q221225AB - 225 Amp Circuit Breaker

Finding the right breaker for existing equipment usually comes down to one thing: matching the existing specifications. The Q221225AB is a 225-amp, 2-pole Q2 molded-case circuit breaker with a Q-Frame design, I-Line plug-on connection, and 2 "A-B" phasing. It uses a thermal-magnetic trip mechanism and carries a 10 kA I.C. rating at 120/240 VAC. Measuring 7.88 inches high, 3.0 inches wide, and 4.31 inches deep, this breaker is intended for compatible electrical equipment that requires this specific combination of frame, mounting style, phasing, and ratings. That makes the Q221225AB especially relevant for maintenance and repair work on legacy electrical systems where keeping the original form, fit, and function is the priority. Simply put, if your existing equipment calls for a 225A, 2-pole Q2 Q-Frame breaker with an I-Line plug-on connection, these are the key specifications you'll want to compare. The breaker is built to last when properly installed, applied, and maintained within its rated application.

Key Features and Benefits

• 225 amp, 2-pole design for systems requiring this specific current rating and pole configuration.
• Q2 Type and Q-Frame construction for compatibility with equipment designed around this breaker style.
• I-Line plug-on connection makes the mounting configuration easy to identify when comparing it with an existing breaker.
• 10k A.I.C. at 120/240VAC provides a clear interrupting and voltage rating for compatibility checks.
• The thermal-magnetic trip mechanism provides overcurrent protection for the intended application.
• 2 "A-B" phasing matches installations that specifically require this phase arrangement.
• Clearly defined dimensions help confirm the physical fit within existing compatible equipment.
• Built to last when used within its specified ratings and properly installed and maintained.

Material Compliance and Certifications

• Certification, listing, and material-compliance requirements can vary by installation, so these details should be verified from the individual breaker's nameplate, labeling, and available product documentation. No certification or material-compliance status should be assumed unless it can be confirmed for the specific unit.
• Before putting the Q221225AB into service, verify that its electrical and physical characteristics meet the equipment requirements. Pay particular attention to the 225A amperage, 2-pole configuration, 120/240VAC rating, 10k A.I.C., Q-Frame design, A-B phasing, and I-Line plug-on connection. Installation should be handled by qualified electrical personnel and in accordance with applicable electrical codes and equipment requirements.

Where It Works Best

• The Q221225AB is a practical fit for maintenance and repair projects involving compatible legacy electrical distribution equipment. It's most relevant when the existing system specifically requires a Q2, Q-Frame, 225-amp, 2-pole breaker with I-Line plug-on mounting and A-B phasing.
