Product FAQs
7 answersWhat type of enclosures are compatible with the QBA220701?
This breaker is designed specifically for installation in Square D I-Line panelboards and switchboards. It will not fit in standard load centers or NQ and NF series panels.
What does the "1" at the end of the QBA220701 catalog number signify?
The "1" indicates that this 2-pole breaker is factory-configured for an AB phase connection on the I-Line busbar stack.
What does the "B" in the QBA prefix represent?
The "B" designates the interrupting capacity of the breaker. For the PowerPacT Q-frame series, a "B" indicates a 10kAIC rating at 240VAC.
Are the standard lugs on this breaker rated for aluminum wire?
Yes, the factory-installed lugs on the QBA220701 are dual-rated for both copper (Cu) and aluminum (Al) conductors ranging from 4 AWG to 300 kcmil.
Is the QBA220701 rated for 100 percent continuous duty?
No, this is a standard-rated circuit breaker. Per NEC guidelines, continuous loads should not exceed 80 percent of its 70-amp rating, which is 56 amps.
Does this breaker include ground fault equipment protection (GFEP)?
No, the QBA220701 is equipped with a standard thermal-magnetic trip unit for overload and short-circuit protection only. It does not provide ground fault or arc fault protection.
How is the QBA220701 secured inside the panelboard?
It utilizes an I-Line plug-in mounting bracket. The breaker jaws plug directly into the panelboard bus stack, and the mounting bracket is secured to the enclosure backpan to hold the breaker firmly in place.
