Designed for 600Y/347V distribution systems, the Siemens BQD6215 is a 2-pole, 15A molded case circuit breaker. It delivers reliable thermal-magnetic protection with a 10kAIC rating, specifically catering to facilities requiring CSA compliance. This bolt-on MCCB mounts securely into Siemens P1, P2, and P3 panelboards. It features a non-interchangeable trip unit and comes equipped with load-side lugs accepting 14-6 AWG copper wire. The breaker includes a trip-free mechanism and is HACR rated.
What panelboards are compatible with the BQD6215 circuit breaker?
This breaker mounts in Siemens P1, P2, and P3 lighting and distribution panelboards. When installing in P2 or P3 panels, a twin-mount hardware kit like the BBKB32 is typically required.
Is the BQD6215 UL listed for use in the United States?
No. The BQD6 series is CSA certified for use in Canada, but it is not UL listed. For a UL listed equivalent at 480Y/277V, you would typically use the standard BQD series.
What does the 6 in the BQD6 prefix indicate?
The 6 indicates that the breaker is rated for 600Y/347V AC systems (CSA only). Standard BQD breakers without the 6 are rated up to 480Y/277V AC.
Does the BQD6215 carry an HACR rating?
Yes, all 1, 2, and 3-pole BQD and BQD6 breakers from 15A to 100A are HACR marked, making them suitable for heating, air conditioning, and refrigeration equipment.
Is this 15A breaker SWD rated for switching fluorescent lighting?
No. While the 1-pole 15A and 20A BQD breakers carry an SWD (Switching Duty) rating, the 2-pole BQD6215 does not.
Can the BQD6215 be mounted on a DIN rail?
BQD and BQD6 breakers can be DIN rail mounted, but they require a specific mounting clip accessory to fit standard 35mm DIN rails (TH35-7.5 or TH35-15). Otherwise, they are designed to bolt directly to the panelboard bus.
Can this breaker be reverse fed?
Yes, Siemens BQD and BQD6 molded case circuit breakers feature a non-interchangeable trip unit and are suitable for reverse feed applications.
Are field-installable accessories available for the BQD6215?
Yes, BQD6 breakers support field-installable internal accessories such as shunt trips, auxiliary switches, and alarm switches. These accessories are typically mounted on the left side of the breaker.
