Product FAQs
8 answersWhat panels are compatible with the Siemens QJH22B110?
This bolt-on breaker is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible Siemens switchboards and multi-family meter centers.
What is the difference between the QJH22B110 and the QJ22B110?
The primary difference is the interrupting capacity. The QJH22B110 has a high interrupting rating of 22kAIC at 240VAC, whereas the standard QJ22B110 is rated for 10kAIC. Both share the same physical QJ frame footprint.
Can I use the QJH22B110 to replace a QJ22B110H?
It depends on the available fault current of your system. The QJH22B110 is rated for 22kAIC, while the QJ22B110H is rated for 42kAIC. If your system requires a 42kAIC rating, the QJH22B110 cannot be used as a direct replacement.
What replacement lug kit is used for the QJH22B110?
The standard replacement lug kit for this QJ frame breaker is the Siemens TA1Q300. This single-barrel lug accepts 6 AWG to 300 kcmil copper or 4 AWG to 300 kcmil aluminum conductors.
Can the Siemens QJH22B110 be reverse fed?
Yes, Siemens QJ frame breakers, including the QJH22B110, feature non-interchangeable trip units and are UL Listed for reverse feed applications.
Is the QJH22B110 HACR rated?
Yes, this breaker is HACR rated, making it suitable for overcurrent protection on heating, air conditioning, and refrigeration equipment circuits.
Does the QJH22B110 feature a removable trip unit?
No, this breaker is built with a fixed thermal-magnetic trip unit that is non-interchangeable. This non-removable design is a requirement for its reverse feed UL listing.
Can I install the QJH22B110 in a standard residential load center?
No, the QJH22B110 is a bolt-on molded case circuit breaker designed for commercial distribution equipment like P-series panelboards and switchboards. It is not compatible with standard plug-on residential load centers.
