Product FAQs
6 answersWhich panelboards accept the QGL22125 circuit breaker?
This Q-frame breaker is designed for use in Square D NQ and NQOD panelboards, as well as compatible switchboards and individual enclosures. It is commonly applied as a main or sub-feed breaker in these systems.
How is the QGL22125 installed in a panelboard?
This is a unit-mount, feed-thru circuit breaker. It does not plug onto a busbar or use an I-Line connection. Instead, it is secured with mounting screws and uses factory-installed lugs on both the line and load sides for hardwired connections.
Can I add field-installable electrical accessories or replacement lugs to this breaker?
No, replacement lugs and field-installable electrical accessories are not available for PowerPacT Q-frame circuit breakers.
What does the G in the QGL22125 catalog number indicate?
The G designates the interrupting rating tier within the PowerPacT Q-frame family. It signifies that the breaker is rated to safely interrupt up to 65kA at 240VAC.
What are the alternate interrupting rating options for this 125A Q-frame breaker?
If your system requires a different short-circuit current rating, Square D offers the QBL22125 (10kA), QDL22125 (25kA), and QJL22125 (100kA). The QGL22125 provides a 65kA rating.
Can the QGL22125 replace older legacy circuit breakers?
Yes, PowerPacT Q-frame breakers are direct replacements for legacy Square D Q2 series devices. The QGL22125 serves as an exact upgrade for the obsolete Q2L2125 breaker.
