Product FAQs
6 answersWhich Siemens panelboards accept the BQ1B020H bolt-on breaker?
The BQ1B020H is compatible with Siemens P1, P2, P3, P4, and P5 commercial panelboards. It features a bolt-on connection that fastens directly to the panel bus for a secure installation in heavy-duty environments.
What is the difference between the Siemens BQ1B020 and BQ1B020H?
The H in the BQ1B020H catalog number indicates a higher interrupting capacity. The BQ1B020H is rated at 22kAIC, while the standard BQ1B020 is rated at 10kAIC. Both share the same physical footprint and bolt-on mounting.
Is the BQ1B020H rated for switching lighting loads?
Yes, this 20-amp breaker is SWD (Switching Duty) rated, which means it is approved for switching 120V fluorescent lighting loads on a regular basis. It is also HACR rated for use with heating, air conditioning, and refrigeration equipment.
Does the BQ1B020H come with load side lugs?
Yes, the breaker includes factory-installed load side lugs that accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. Line side connections are made via the bolt-on mounting directly to the panelboard bus.
Is the BQ1B020H suitable for 277V commercial lighting circuits?
No. While it is a commercial bolt-on breaker, the BQ1B020H is strictly rated for 120VAC maximum. For 277V lighting circuits, a different breaker family such as the Siemens BQD series is required.
Will the Siemens BQ1B020H replace an older ITE BQ1B020H?
Yes. Siemens acquired the ITE electrical line and continues to manufacture the BQ and BQH series to the original specifications. A modern Siemens BQ1B020H is a direct, code-compliant replacement for an ITE breaker with the exact same catalog number.
