Product FAQs
7 answersWhich Siemens panelboards accept the BQD180 circuit breaker?
This bolt-on breaker is compatible with Siemens P1, P2, P3, P4, and P5 panelboards. It is designed specifically for panelboard mounting and cannot be installed on a DIN rail.
Is the BQD180 HACR rated for HVAC equipment?
Yes, Siemens BQD frame breakers in this amperage range are HACR rated, making them suitable for heating, air conditioning, and refrigeration branch circuit protection.
Can the BQD180 be used for switching fluorescent or HID lighting?
No. While the BQD frame offers Switching Duty (SWD) and High Intensity Discharge (HID) ratings on lower amperages, the 80A BQD180 exceeds the maximum amperage for these specific lighting ratings. SWD is limited to 15-20A, and HID is limited to 15-50A for 1-pole models.
What are the acceptable wire sizes for the BQD180 lugs?
The factory-installed lugs accept 8 to 1 AWG copper (Cu) conductors or 6 to 1/0 AWG aluminum (Al) conductors.
What is the difference between the Siemens BQD180 and the CQD equivalent?
The BQD180 is a bolt-on breaker designed for Siemens panelboards. The CQD version shares the same internal frame and electrical ratings but is configured for DIN rail or surface mounting in control panels.
Is the Siemens BQD180 suitable for reverse feed applications?
Yes, Siemens BQD circuit breakers are approved for reverse feed applications, allowing them to be back-fed when used as a main breaker or in specific control configurations.
Does the BQD180 support DC voltage applications?
Yes, in addition to its AC ratings, this breaker is rated for 125VDC systems, providing a 14kAIC interrupting capacity for DC control or battery circuits.
