Product FAQs
5 answersCan I install the BQ2B015 in a standard residential plug-on load center?
No. The BQ2B015 features a bolt-on connection designed for commercial Siemens P1, P2, and P3 panelboards. It cannot be used in standard residential load centers that require plug-on type circuit breakers.
Are higher interrupting rating versions available for this 15-amp breaker?
Yes. If your electrical system requires a higher interrupting rating than the standard 10kAIC, you can use catalog number BQ2B015H for 22kAIC or HB2B015 for 65kAIC applications.
Does the BQ2B015 come equipped with line and load lugs?
This breaker is supplied with load-side lugs as standard. Line-side lugs are not included because the breaker is designed to bolt directly to the panelboard bus bar. If line-side lugs are needed for a specific application, a specialized variant with an "L" suffix is required.
Is the Siemens BQ2B015 suitable for HVAC equipment?
Yes, this circuit breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment loads.
What is the difference between Siemens BQ and BQD circuit breakers?
While both series share the same 1-inch per pole width and bolt-on mounting style, they are designed for different voltage limits. BQ breakers are rated for systems up to 240VAC, whereas BQD breakers are rated for higher voltages up to 480Y/277VAC.
