Product FAQs
6 answersWhat type of panelboard accepts the Q232175H circuit breaker?
This breaker features an I-Line style plug-on connection designed exclusively for Square D I-Line panelboards and switchboards. It will not fit in NQ, NF, or QO load centers.
Is the Q232175H a current production model?
No, the Q2 frame is a legacy series that has been discontinued by Schneider Electric. The direct modern replacement for this I-Line breaker is the PowerPact Q-frame series, specifically the QDA32175.
What are the wire size and torque requirements for the load lugs?
The standard mechanical lugs accept 4 AWG to 300 kcmil copper or aluminum conductors. The required tightening torque for these terminals is 250 lb-in.
What does the H suffix mean in the Q232175H part number?
The H indicates a High Interrupting Capacity rating. Standard Q2 breakers typically offer a 10kAIC rating, whereas this model provides an upgraded 22kAIC at 240VAC.
Can the Q232175H be installed in 480V or 600V systems?
No, this breaker is strictly rated for a maximum of 240VAC. It is not suitable for 480V or 600V distribution systems.
Does the Q232175H feature an adjustable trip unit?
No, this breaker utilizes a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory set and cannot be adjusted in the field.
