Product FAQs
8 answersWhat enclosures are compatible with the QJL22070 circuit breaker?
This unit-mount breaker installs in Square D PowerPacT Q-Frame enclosures, as well as compatible panelboards and switchboards designed for Q-Frame devices.
Can the QJL22070 replace older Square D breakers?
Yes, the PowerPacT Q-Frame series serves as a direct modern replacement for legacy Square D Q2 Series circuit breakers.
What wire sizes do the lugs on the QJL22070 accept?
The factory-installed box lugs accept 4 AWG to 300 kcmil aluminum or copper conductors.
Does the QJL22070 plug into a load center busbar?
No, this is a unit-mount, feed-thru breaker. It requires hardwired connections at both the line and load ends using the provided lugs, and it fastens with mounting screws rather than plugging onto a busbar.
What does the L in the QJL22070 catalog number indicate?
In the PowerPacT Q-Frame nomenclature, the L indicates that the breaker is supplied with factory-installed lugs on both the line and load ends.
Are the trip settings adjustable on the QJL22070?
No, this breaker uses a fixed thermal-magnetic trip unit. Both the long-time thermal and instantaneous magnetic trip functions are factory-set and non-adjustable.
Is the QJL22070 HACR rated?
Yes, Square D PowerPacT Q-Frame breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.
Can this 2-pole breaker be used on a 3-phase system?
The QJL22070 is a 2-pole breaker intended for single-phase applications or across two phases of a 3-phase system, provided the system voltage does not exceed its 240VAC rating.
