Product FAQs
5 answersWhich panelboards accept the Siemens BQ3B02000S01 circuit breaker?
This 3-pole bolt-on breaker is designed for installation in Siemens P1, P2, and P3 panelboards. It is also fully compatible with legacy ITE panelboards that utilize BQ series branch breakers.
Can I use this to replace an older ITE BQ3B02000S01 breaker?
Yes. Siemens acquired ITE and maintained the BQ product line. The modern Siemens BQ3B02000S01 is a direct, drop-in replacement for the legacy ITE version with the exact same catalog number.
What does the S01 suffix mean in the BQ3B02000S01 catalog number?
The S01 suffix indicates the inclusion of a factory-installed 120V AC shunt trip. This accessory allows the breaker to be tripped remotely via an external voltage signal, which is commonly used for emergency stops or automated safety shutdowns.
What wire gauges are supported by the load lugs on this 20A breaker?
When wiring the BQ3B02000S01, the integrated load lugs accept 14 AWG to 6 AWG copper wire or 12 AWG to 6 AWG aluminum wire, providing flexibility for various conductor types in 20A branch circuits.
What trip technology is used in the BQ3B02000S01?
It utilizes a fixed thermal-magnetic trip unit providing LI (Long-Time and Instantaneous) protection. The thermal element responds to sustained overloads, while the magnetic element trips instantly during short circuits.
