Product FAQs
7 answersCan the QDA221102 be installed in older Square D I-Line panelboards?
Yes. Schneider Electric has evaluated older I-Line panelboards and switchboards and confirmed they accept newer PowerPacT Q-frame breakers like the QDA221102, provided the voltage and interrupting ratings meet your system requirements.
Is the PowerPacT Q-frame a replacement for older Square D breakers?
Yes, PowerPacT Q-frame circuit breakers are direct replacements for legacy Square D Q2 Series devices.
How does this breaker connect to the panelboard?
The QDA221102 features an I-Line plug-in connection on the line side that mounts directly to the bus of Square D I-Line panelboards and switchboards, with mechanical box lugs on the load side for cable connections.
What wire sizes do the load lugs on the QDA221102 accept?
The factory-installed box-type lugs on the load side accept 4 AWG to 300 kcmil aluminum or copper conductors.
Does the QDA221102 have a manual trip feature?

Is the QDA221102 rated for 100% continuous current?
No, this breaker is standard-rated, meaning it is designed to carry a continuous load of up to 80% of its 110A nameplate rating.
