Product FAQs
6 answersWhat does the S01 suffix mean on the BQ3B10000S01 catalog number?
The S01 suffix indicates this breaker is factory-equipped with a 120V AC shunt trip accessory, which allows the breaker to be tripped remotely via an external control signal.
Is this breaker compatible with legacy ITE panelboards?
Yes, Siemens BQ series breakers are fully backward compatible with legacy ITE panelboards, as well as modern Siemens P1, P2, and P3 panelboards.
Does the BQ3B10000S01 use a plug-in or bolt-on connection?
This is a bolt-on circuit breaker. It requires a bolted connection to the panelboard bus, providing a secure mechanical and electrical connection for commercial and industrial applications.
Can aluminum wire be used with the BQ3B10000S01 lugs?
Yes, the standard lugs on this breaker are dual-rated for both copper (8 to 1 AWG) and aluminum (6 to 1/0 AWG) conductors.
Are the thermal-magnetic trip settings adjustable on this model?
No, the BQ3B10000S01 features a fixed thermal-magnetic trip unit. The Long-Time and Instantaneous (LI) trip functions are factory preset and cannot be adjusted in the field.
Does the integrated shunt trip require a separate control circuit?
Yes, the factory-installed shunt trip requires a dedicated 120V AC control voltage signal to remotely open the breaker contacts.
