Product FAQs

8 answers
Is the Square D QGL22150 an I-Line or unit-mount breaker?

The QGL22150 features a unit-mount, feed-thru design with lugs on both the line and load ends. It is not an I-Line group-mounted breaker. It is designed to be hardwired and installed in NQ panelboards, NQOD panelboards, switchboards, or individual enclosures.

What legacy Square D breaker does the QGL22150 replace?

The PowerPacT QGL22150 serves as a direct physical and functional replacement for the discontinued Square D Q2L2150 circuit breaker. It fits the same footprint while offering an upgraded 65 kAIC interrupting rating.

How does the QGL22150 differ from the QGA22150?

Both are 150-amp, 2-pole PowerPacT Q-Frame breakers with a 65 kAIC rating at 240V. However, the QGL22150 is a unit-mount breaker equipped with mechanical lugs on both ends, whereas the QGA22150 is an I-Line breaker designed to plug directly into an I-Line distribution bus.

What are the magnetic trip thresholds for the 150A QGL22150?

This 150A thermal-magnetic breaker features a fixed instantaneous magnetic trip. The factory setting provides a magnetic hold current of 1200A and a magnetic trip current of 2400A.

What does the G signify in the QGL22150 catalog number?

In the Square D PowerPacT Q-Frame nomenclature, the G designates the interrupting rating. It indicates that the circuit breaker has a short-circuit current rating of 65 kA at 240V AC.

Are the line and load lugs included with the QGL22150?

Yes, the QGL22150 ships with factory-installed mechanical lugs on both the line and load sides. The lugs are rated for aluminum or copper conductors ranging from 4 AWG to 300 kcmil.

Can I install this 2-pole QGL breaker in a 3-phase NQ panelboard?

Yes, you can install this 2-pole breaker in a 3-phase NQ or NQOD panelboard to supply a single-phase 240V load. You will need to procure the correct unit-mount breaker installation kit specific to your panelboard model.

Is the QGL22150 suitable for HVAC motor loads?

Yes, this molded case circuit breaker carries a HACR rating, making it fully approved for use in heating, air conditioning, and refrigeration equipment circuits.
