Product FAQs
7 answersWhich panelboards are compatible with the Siemens QJH23B225?
This bolt-on circuit breaker is designed for direct installation into Siemens P1, P2, P3, P4, and P5 panelboards. It is also compatible with Siemens switchboards and modular meter centers.
Is the QJH23B225 circuit breaker suitable for 480V or 600V systems?
No, this breaker is strictly rated for a maximum of 240VAC. It cannot be used in 480V or 600V electrical distribution systems.
What are the allowable wire gauges and materials for the standard lugs on this breaker?
The lugs on the QJH23B225 accept copper conductors ranging from 6 AWG to 300 kcmil, and aluminum conductors ranging from 4 AWG to 300 kcmil.
How does the QJH23B225 differ from the QJ23B225?
The difference lies in the short circuit interrupting capacity. The standard QJ23B225 provides 10kAIC at 240V, whereas the QJH23B225 provides a higher interrupting rating of 22kAIC at 240V. Both share the same physical dimensions and bolt-on mounting configuration.
Can the trip curve be adjusted on the QJH23B225?
No, this breaker features a thermal magnetic trip unit with fixed thermal and fixed magnetic settings. The Long-Time and Instantaneous trip functions cannot be modified in the field.
Has the Siemens QJ frame series been replaced by a newer form factor?
Yes, Siemens has transitioned from the legacy QJ frame to the newer QR frame series. The QR frame breakers feature the exact same dimensions and mounting configuration as the QJH23B225, allowing for a seamless retrofit in existing panelboards.
Do I need a mounting kit to install the QJH23B225 into a Siemens panelboard?
Yes, installing this breaker into Siemens panelboards typically requires a branch breaker mounting hardware kit, such as the BBKQ1 for P2 panels or the SQJ kit for dual branch configurations. Verify the exact hardware required for your specific panel enclosure.
