Product FAQs
8 answersCan I use the BQD315 in a standard Siemens residential load center?
No. BQD breakers feature a bolt-on connection designed for commercial P-series panelboards (P1 through P5). They are not compatible with residential EQ or PL load centers, which require plug-on or QP-style breakers.
Is the BQD315 circuit breaker suitable for reverse feed applications?
Yes, standard Siemens BQD molded case circuit breakers are approved and listed for reverse feed installations.
What does the HACR rating on this breaker signify?
The HACR designation indicates the breaker is tested and UL listed for safe use with Heating, Air Conditioning, and Refrigeration equipment, meaning it can safely handle the specific motor inrush currents associated with those loads.
Does this breaker carry an SWD (Switching Duty) rating?
No. While Siemens provides SWD ratings for 1-pole 15A and 20A BQD breakers used to switch fluorescent lighting, 3-pole models like the BQD315 do not carry the SWD mark.
What is the difference between Siemens BQD and CQD series breakers?
Both series share identical dimensions and internal trip mechanisms, but their mounting configurations differ. BQD breakers are built for bolt-on panelboard mounting, while CQD breakers are designed for surface mounting or attachment to a standard DIN rail.
Is the BQD315 rated for 100% continuous duty?
No. Like most standard commercial molded case circuit breakers, the BQD315 carries an 80% continuous duty rating. Continuous loads should not exceed 80% of its 15-amp rating, which equals 12 amps.
Is this breaker approved for High-Intensity Discharge (HID) lighting?
Yes, 3-pole Siemens BQD circuit breakers in the 15A to 50A range carry an HID rating at 480Y/277V AC, making them fully suitable for high-intensity discharge lighting circuits.
Can I install the BQD315 on a 3-phase delta 480V grounded B phase system?
No, Siemens specifically restricts BQD circuit breakers from being used in 3-phase delta 480V grounded B phase applications. They are intended for use on 480Y/277V solidly grounded Wye systems.
