Product FAQs
7 answersHow does the interrupting rating of the QJL32110 change depending on the system voltage?
While rated for 100 kAIC at 208Y/120 VAC on a 3-phase, 4-wire system, the interrupting capacity drops to 65 kAIC when applied to a 240/120 VAC 3-phase, 4-wire delta system.
What wire sizes are accepted by the factory lugs on the QJL32110?
The standard box lugs on this Q-frame breaker accommodate #4 AWG through 300 kcmil copper or aluminum conductors.
What are the instantaneous magnetic trip thresholds for the QJL32110?
This 110A thermal-magnetic breaker has a fixed magnetic hold setting of 1200A and a magnetic trip setting of 2400A.
What is the I-Line panelboard equivalent for the QJL32110?
The QJL32110 is a unit-mount breaker with lugs on both ends. For I-Line group-mounted applications, the correct catalog number is QJA32110.
What are the lower interrupting capacity equivalents for this 110A Q-frame breaker?
If your system does not require a 100 kAIC rating, you can use the QBL32110 for 10 kAIC, QDL32110 for 25 kAIC, or QGL32110 for 65 kAIC.
Can the QJL32110 be installed in a standalone enclosure?
Yes, this unit-mount breaker can be installed in Square D Q-frame circuit breaker enclosures. Ensure the enclosure is rated for a 3-pole breaker and meets the NEMA rating required for your environment.
Can I add field-installable electrical accessories to the QJL32110?
No, electrical accessories such as shunt trips or auxiliary switches, as well as replacement lugs, are not available for field installation on PowerPacT Q-frame circuit breakers.
