Product FAQs
6 answersWhat does the "H" in the QJ23B090H catalog number signify?
The "H" indicates a high interrupting capacity. The QJ23B090H provides a 42kAIC rating at 240VAC, compared to the standard QJ23B090 which is rated at 10kAIC, and the QJH23B090 rated at 22kAIC.
Is the QJ23B090H a direct replacement for lower-AIC QJ-frame breakers?
Yes. It shares the exact physical dimensions and bolt-on mounting footprint as the 10kAIC QJ23B090 and the 22kAIC QJH23B090. It can be used as a drop-in upgrade when a 42kAIC fault rating is required by the system study.
Can the QJ23B090H be installed in a standard plug-on load center?
No. This is a bolt-on molded case circuit breaker designed for commercial panelboards and switchboards. It will not fit in residential plug-on load centers that use QP or QT series breakers.
Are the thermal and magnetic trip settings adjustable on this breaker?
No. The QJ23B090H features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory set and non-adjustable.
Can this 3-pole breaker be used in a single-phase panel?
No. The QJ23B090H is a 3-pole breaker built for 3-phase, 240VAC systems. Single-phase applications require a 2-pole QJ-frame breaker, such as the QJ22B090H.
Does this breaker include load-side lugs?
Yes, the QJ23B090H comes standard with factory-installed load-side lugs. The line side bolts directly to the panelboard bus.
