Product FAQs
8 answersWhat type of panelboard accepts the Square D Q232225 circuit breaker?
This breaker features an I-Line style plug-in connection designed specifically for Square D I-Line panelboards and switchboards. It is not compatible with standard QO or Homeline load centers.
Is the Q232225 Q-Frame breaker still used in new construction?
The Square D Q232225 is part of the legacy Q-Frame family and is generally considered obsolete for new installations. It is primarily sourced as a direct, form-fit replacement to maintain existing I-Line distribution systems without requiring a complete panelboard upgrade.
How does the Q232225 connect to the power bus and load wires?
The line side features an I-Line plug-on connection that mounts directly to the panelboard bus structure, while the load side is equipped with mechanical lugs that accept 4 AWG to 300 kcmil aluminum or copper wire.
Can the trip curve be adjusted on the Q232225 breaker?
No, the thermal-magnetic trip unit on this model is non-interchangeable and features fixed long-time (L) and instantaneous (I) trip functions. The settings cannot be adjusted in the field.
What does the 10kAIC interrupting rating mean for safety and installation?
The 10kAIC rating indicates the maximum fault current the breaker can safely clear at 240VAC. Before installing this replacement, you must verify that the available short-circuit current at the panel does not exceed 10,000 amps to maintain a safe electrical system.
Is the Q232225 compatible with 480V systems?
No. This breaker is rated for a maximum of 240VAC. Installing it in a 480V or 600V system is a severe safety violation and will lead to equipment failure.
Does this breaker require a separate mounting kit for installation?
No additional mounting hardware is required for the line side, as the I-Line plug-in jaws are integrated into the breaker body and secure directly to the panelboard bus assembly.
Are the load lugs included with the Q232225 breaker?
Yes, this model comes factory-equipped with mechanical lugs on the load side that accept standard aluminum and copper conductors.
