Product FAQs

6 answers
What is the difference between QBL, QDL, QGL, and QJL circuit breakers?

These prefixes identify the short-circuit interrupting rating of the PowerPacT Q-Frame breakers at 240VAC. The QBL is rated 10kAIC, QDL is 25kAIC, QGL is 65kAIC, and QJL is 100kAIC.

Is the QDL32150 a direct replacement for the legacy Q2L3150?

Yes, the PowerPacT QDL32150 is a direct, seamless replacement for the discontinued Square D Q2L3150 circuit breaker.

Are the line and load lugs included with this unit?

Yes, this feed-thru circuit breaker comes equipped with factory-installed lugs on both the line and load ends, accepting 4 AWG to 300 kcmil copper or aluminum wire.

How does a unit mount breaker install in a panel?

Unit mount breakers are fastened directly to the panel backpan using mounting screws and are wired via cable connections to the lugs, unlike plug-on or I-Line bus-mounted breakers.

Can the QDL32150 be installed in a Square D NQ panelboard?

Yes, Q-Frame breakers can be installed in NQ panelboards where they are commonly utilized as main or sub-feed circuit breakers.

Is this breaker suitable for use on a 208Y/120V system?

Yes, the QDL32150 is fully rated for 208Y/120VAC systems and provides the same 25kAIC interrupting capacity as it does at 240VAC.
