Product FAQs
6 answersWhat enclosures and panels are compatible with the QBL22090 circuit breaker?
The QBL22090 is designed for use in Square D Q2 enclosures, switchboards, control panels, and meter mains.
What wire sizes are accepted by the lugs on the QBL22090?
The line and load lugs accept 4 AWG to 300 kcmil aluminum or copper wire.
What is the recommended tightening torque for the lug terminals on this breaker?
The line and load lugs should be torqued to 248 lb-in (28 N.m).
What is the difference between the QBL22090 and the QDL, QGL, or QJL versions?
The difference is the interrupting rating at 240V. The QBL22090 is rated at 10kA, while the QDL is 25kA, the QGL is 65kA, and the QJL is 100kA. They share the same physical dimensions and mounting style.

The LI designation stands for Long-Time and Instantaneous trip functions. This breaker uses fixed thermal and fixed magnetic trip settings to protect against overloads and short circuits.
Is the QBL22090 a plug-on or bolt-on breaker?
Neither. It is a unit-mount, feed-thru circuit breaker that uses lugs on both the line and load sides for wire connections. It does not plug or bolt onto a panelboard bus.
