Product FAQs
7 answersWhich panelboards accept the BQD1100 circuit breaker?
It is compatible with Siemens P1, P2, P3, P4, and P5 panelboards. Depending on the specific panel generation and interior configuration, a dedicated mounting strap kit may be required for installation.
Is the BQD1100 suitable for direct current systems?
Yes, it carries a 125VDC rating with a 14kA interrupting capacity. This makes it a viable option for industrial DC control panels, battery systems, and specific automation applications requiring a 100A single-pole breaker.
Does this breaker include ground fault or arc fault protection?
No, the BQD1100 is a standard thermal-magnetic breaker equipped with fixed long-time and instantaneous trip functions. It does not provide GFCI or AFCI protection.
Can the BQD1100 be installed on a standard DIN rail?
While it is natively a bolt-on breaker for panelboards, Siemens manufactures compatible DIN rail adapter kits. These adapters allow the breaker to be mounted in standard control cabinets and automation panels.
What is the advantage of the bolt-on connection for this breaker?
Bolt-on breakers like the BQD1100 are fastened directly to the busbar or mounting strap with screws. This creates a highly secure mechanical and electrical connection that resists loosening from thermal cycling or heavy vibrations in industrial environments.
Can the trip settings on the BQD1100 be adjusted in the field?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip thresholds are factory set and cannot be modified by the installer.
Does the BQD1100 require special lugs for aluminum wiring?
No, the factory-installed lugs are AL/CU rated. They safely accept both copper and aluminum conductors without requiring a lug swap.
