Product FAQs
6 answersWhich panelboards are compatible with the QJH23B090 circuit breaker?
This breaker is designed for use in Siemens P1, P2, P3, P4, and P5 panelboards, as well as compatible switchboards and meter centers. Depending on the specific panelboard model, a separate mounting strap kit may be required for installation.
What does the H in the QJH23B090 catalog number signify?
The H indicates a high interrupting capacity. While standard QJ23B090 breakers are typically rated at 10kAIC, the QJH23B090 provides a higher 22kAIC rating at 240VAC.
Are the factory lugs on the QJH23B090 rated for aluminum wire?
Yes, the included load-side lugs accept both copper and aluminum conductors. The supported wire range is 6 AWG to 300 kcmil for copper, and 4 AWG to 300 kcmil for aluminum.
Is the QJH23B090 interchangeable with newer QR frame breakers?
Yes. The QJH23B090 is an original QJ frame breaker, but Siemens designed the newer QR frame series with the exact same form factor and mounting footprint. This allows QR breakers to serve as direct retrofits for legacy QJ and QJH frames.
Does the QJH23B090 snap into place or bolt onto the bus?
The QJH23B090 is a bolt-on molded case circuit breaker. It requires a bolted connection to the panelboard bus or a dedicated mounting strap, ensuring a secure connection for commercial and industrial applications.
Can I adjust the trip settings on the QJH23B090?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time thermal and instantaneous magnetic trip functions are factory-set and cannot be adjusted in the field.
