Product FAQs
5 answersCan I install the QO210 in a Square D Homeline load center?
No. Square D QO and Homeline circuit breakers are not interchangeable. The QO210 is designed exclusively for QO load centers, NQ panelboards, and legacy NQOD panelboards.
Is there a bolt-on equivalent for the QO210?
Yes. If your panelboard requires a bolt-on connection rather than a plug-on mount, the equivalent breaker is the QOB210.
Can the QO210 be used in DC control circuits?
Yes, this thermal magnetic breaker is rated for DC applications up to 48VDC, providing a 5kA interrupting capacity for low-voltage control or battery circuits.
Does this breaker feature a tripped-state indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips, a highly visible red flag appears in the window to help quickly identify the faulted circuit in the panel.
Will the pressure plate terminals accept aluminum wiring?
Yes, the terminals are dual-rated for both aluminum and copper conductors. They accept wire gauges from 14 AWG to 8 AWG.
