Product FAQs
6 answersWhich Siemens panelboards accept the QJ23B17500S01 circuit breaker?
This QJ frame breaker mounts directly into Siemens P1, P2, and P3 panelboards. It is also compatible with Siemens switchboards and modular enclosures designed for bolt-on QJ or QR frame breakers.
What does the 00S01 suffix indicate on the QJ23B17500S01?
The 00S01 suffix designates a factory-installed 120/240V AC shunt trip. This allows the breaker to be opened remotely from a control circuit for emergency power-off or equipment interlocks.
Can I field-install a shunt trip on a standard QJ23B175 breaker?
No. Internal accessories for the QJ frame, such as the shunt trip found on the QJ23B17500S01, are factory-installed only and cannot be added in the field.
What is the modern replacement for the QJ23B17500S01?
Siemens has replaced the QJ frame with the QR frame. The modern equivalent is the QR23B175. To match the shunt trip functionality, you must also install an S01QR2 shunt trip kit.
Is the QJ23B17500S01 suitable for reverse feed applications?
Yes, Siemens QJ frame molded case circuit breakers are UL Listed for reverse feed applications.
Are the trip units on the QJ23B17500S01 interchangeable?
No, this breaker features a non-interchangeable thermal magnetic trip unit with fixed long-time and instantaneous trip functions.
