Product FAQs
7 answersWhich panelboards are compatible with the Siemens BQ3B01500S01 circuit breaker?
This bolt-on breaker is designed for use in Siemens P1, P2, and P3 panelboards, as well as legacy ITE panelboards that accept BQ frame breakers.
Can I install this breaker in a standard residential load center?
No. The BQ3B01500S01 is a bolt-on circuit breaker designed specifically for commercial panelboards. It is not compatible with standard plug-on residential load centers.
What does the 00S01 suffix indicate on this circuit breaker?
The 00S01 suffix indicates that this breaker includes a factory-installed 120V AC shunt trip mechanism. This allows the breaker to be tripped remotely via a control circuit for emergency power-off or equipment interlocks.
Can the shunt trip mechanism be added or removed in the field?
No. The 120V AC shunt trip on the BQ3B01500S01 is factory-installed and cannot be added, removed, or modified in the field. If a standard breaker without a shunt trip is needed, a different catalog number must be used.
What wire sizes are accepted by the terminal lugs on this breaker?
The load side lugs accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
Are the trip settings on the BQ3B01500S01 adjustable?
No. This thermal-magnetic breaker features fixed Long-Time and Instantaneous (LI) trip functions. The thermal and magnetic trip points are set at the factory and cannot be adjusted in the field.
Can this breaker replace older ITE versions?
Yes. Siemens acquired ITE, and this breaker serves as a direct replacement for legacy ITE BQ3B01500S01 circuit breakers used in older ITE panelboards.
