Product FAQs
7 answersHow much mounting space does the QJA32150 require on an I-Line bus?
A 3-pole PowerPacT Q-frame circuit breaker requires 4.5 inches of I-Line bus mounting space. Each pole takes up 1.5 inches of width on the bus assembly.
What is the difference between QBA32150, QDA32150, QGA32150, and QJA32150?
These catalog numbers share the same 150A Q-frame physical dimensions and thermal-magnetic trip characteristics, but they offer different interrupting ratings. The QJA has the highest rating at 100kA at 240VAC. Lower rated versions include the QBA (10kA), QDA (25kA), and QGA (65kA).
Can the QJA32150 be reverse fed?
Yes, PowerPacT Q-frame thermal-magnetic circuit breakers are suitable for forward or reverse feeding. When utilizing this breaker as a back-fed main, ensure you install the appropriate retaining hardware required by the panelboard and local electrical codes.
Is the QJA32150 suitable for 480V or 600V electrical systems?
No, the QJA series is rated for a maximum of 240VAC. It cannot be safely applied on 480V, 480Y/277V, or 600V systems.
Which Square D panelboards accept the QJA32150 circuit breaker?
This plug-on unit is designed exclusively for Square D I-Line panelboards and switchboards. It will not fit in NQ, NF, or standard residential QO load centers.
Can aluminum wire be used with the standard lugs on this 150A breaker?
Yes, the factory box lugs on the 150A Q-frame accept either aluminum or copper conductors sized from 4 AWG to 300 kcmil.
What phase jaw configuration does the standard QJA32150 feature?
The base catalog number without any suffix indicates a standard ABC phase jaw configuration for the I-Line bus connection.
