Product FAQs
7 answersWhat panelboards accept the QDL22100 circuit breaker?
This PowerPacT Q-frame breaker is commonly used as a main or sub-feed breaker in Square D NQ panelboards. It can also be installed in Square D switchboards and individual enclosures.
What does a feed-thru connection mean for this Q-frame breaker?
A feed-thru connection indicates that the breaker is unit-mounted and comes equipped with box lugs on both the line and load sides, rather than plugging onto a bus or bolting into an I-Line panel.
What is the lug torque specification for the QDL22100?
The factory lugs on this breaker should be torqued to 247.8 lb-in (28 N.m). They accept 4 AWG to 300 kcmil aluminum or copper conductors.
What is the difference between Square D QDL, QGL, and QJL breakers?
The third letter in the prefix designates the maximum interrupting rating at 240VAC. The QDL is rated for 25kAIC, the QGL is rated for 65kAIC, and the QJL is rated for 100kAIC.
Can the QDL22100 replace older Square D Q2 series breakers?
Yes, the modern PowerPacT Q-frame circuit breakers are designed as direct replacements for legacy Square D Q2 series devices.
Is the QDL22100 rated for 100 percent continuous current?
No, this breaker has a standard 80 percent continuous current rating. It is not rated to carry its full 100A capacity continuously.
Does this breaker include ground fault or arc fault protection?
