Product FAQs
5 answersWhat is the difference between Siemens CQD and BQD circuit breakers?
The CQD series, including the CQD1100, is designed for 35mm DIN rail mounting. The BQD series is designed for panel mounting or bolt-on applications. Both share the same internal mechanisms and electrical ratings.
Can I install the CQD1100 in a standard Siemens load center?
No, the CQD1100 is a DIN rail mounted breaker and is not compatible with standard plug-on or bolt-on load centers. It is intended for use in DIN rail enclosures and OEM control panels.
What is the panel mount equivalent to the CQD1100?
If your application requires a bolt-on connection rather than a DIN rail mount, the Siemens BQD1100 offers the exact same 100A rating and trip characteristics for panelboard installations.
Can the CQD1100 be used in DC circuits?
Yes, this breaker is rated for DC applications up to 125VDC with an interrupting capacity of 14kA, making it suitable for specific control panel and battery system applications.
Does the CQD1100 provide ground fault or arc fault protection?
No, this is a standard thermal magnetic breaker providing only long time overload and instantaneous short circuit protection. It does not include equipment protection, GFCI, or AFCI circuitry.
