Product FAQs
5 answersWhat does the 00S01 suffix indicate on the Q39000S01 catalog number?
The 00S01 suffix means the breaker includes a factory-installed 120V AC shunt trip. This allows the breaker to be opened remotely via a 120V control signal, which is commonly used for emergency stops or automated power disconnection.
How many 1-inch panel spaces are required to install the Q39000S01?
This breaker requires four 1-inch panel spaces. The 3-pole breaker occupies three spaces, and the attached shunt trip module requires one additional adjacent space.
Which load centers and panelboards are compatible with this breaker?
The Q39000S01 is designed for use in Siemens EQ and Ultimate load centers, as well as Siemens P1 panelboards that accept plug-on QP series branch breakers.
What control voltage is required to activate the shunt trip mechanism?
The factory-installed shunt trip on this specific model requires a 120V AC control voltage signal to remotely trip the breaker contacts.
Does this breaker provide ground fault or arc fault protection?
No. The Q39000S01 is a standard thermal magnetic breaker with long-time and instantaneous (LI) trip functions. It does not include GFCI or AFCI protection.
