Product FAQs
6 answersHow is the Siemens BQ2B030QLD secured within an enclosure?
It snaps directly onto standard 35mm DIN rails commonly found in industrial control panels and OEM enclosures. The integrated mounting clip eliminates the need for separate bolt-on brackets or specialized busbars.
Are line and load lugs included with this breaker?
Yes, the BQ2B030QLD comes factory-equipped with both line and load side lugs. They accommodate 16 to 6 AWG copper or 12 to 6 AWG aluminum conductors.
What does the QLD suffix indicate on this Siemens BQ series breaker?
The QLD suffix specifies that the breaker is configured for DIN rail mounting and includes line and load lugs. This differentiates it from standard bolt-on or plug-in BQ breakers used in traditional panelboards.
Can the BQ2B030QLD be used in standard Siemens residential load centers?
No. Because it features a DIN rail mounting mechanism rather than a plug-in or standard bolt-on clip, it is strictly intended for DIN rail enclosures and OEM control panels.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic mechanism delivers long-time response for sustained overloads and an instantaneous response to clear short circuits, protecting sensitive industrial control circuits.
Is the BQ2B030QLD considered a Type BQXD breaker?
Yes, this model falls under the Siemens Type BQXD classification, which designates low-voltage molded case circuit breakers equipped with DIN rail mounting hardware and lugs for control panel applications.
