Product FAQs
7 answersHow is the Siemens BQ2B020QLD secured within an enclosure?
The BQ2B020QLD features a built-in DIN rail mounting mechanism, allowing it to snap directly onto standard 35mm DIN rails commonly found in OEM panels and industrial control enclosures.
What does the QLD suffix signify in the BQ2B020QLD part number?
In the Siemens BQ series, the QLD suffix indicates that the circuit breaker is configured for DIN rail mounting and comes factory-equipped with both line and load side lugs.
What type of terminations are provided on the BQ2B020QLD?
This breaker features factory-installed mechanical lugs on both the line and load sides, which accept up to 6 AWG copper or aluminum conductors for direct wire connections in control panels.
How does the thermal magnetic trip unit operate on this breaker?
The breaker utilizes fixed thermal and fixed magnetic elements to provide a long-time delay for overload conditions and instantaneous tripping for short circuits.
Can the BQ2B020QLD be installed in standard Siemens residential load centers?
No. While standard BQ breakers are bolt-on and QP breakers are plug-on for load centers, the QLD variant is specifically designed for DIN rail enclosures and OEM control panels.
Are both poles internally connected for common tripping?
Yes, this 2-pole breaker features a common-trip mechanism, ensuring that an overcurrent event on either phase will simultaneously open both poles to safely disconnect the circuit.
Does this breaker provide ground fault or arc fault protection?
No, the BQ2B020QLD is a standard thermal magnetic breaker designed for general purpose overcurrent and short circuit protection. It does not feature GFCI or AFCI capabilities.
