Product FAQs
7 answersWhat do the "H" and "00S01" suffixes mean in the QJ23B175H00S01 catalog number?
The "H" indicates that this is a high-interrupting QJ2H frame rated at 42kAIC at 240V AC. The "00S01" suffix designates a factory-installed 120/240V AC shunt trip.
Is the Siemens QJ23B175H00S01 still in active production?
No, the Siemens QJ frame has been discontinued and replaced by the QR frame. The QR series shares the exact same form factor and mounting configuration for direct retrofitting into existing panels.
Which panelboards accept the QJ23B175H00S01 circuit breaker?
This bolt-on breaker is compatible with Siemens P1, P2, and P3 panelboards, as well as Siemens meter centers and enclosures.
Can the thermal-magnetic trip unit be swapped in the field?
No. Siemens QJ frame circuit breakers are built with non-interchangeable trip units. The breaker is shipped fully assembled and the trip unit cannot be removed or modified.
Is the QJ23B175H00S01 UL Listed for reverse feed applications?
Yes. Because the trip unit is non-interchangeable, this QJ frame breaker is UL Listed and suitable for reverse feed applications where power flows from the load side to the line side.
Can I add auxiliary switches or other internal accessories to this breaker in the field?
No. Internal accessories for Siemens QJ frame breakers, including shunt trips and auxiliary switches, are factory-installed only and cannot be added or modified in the field.
