Product FAQs
8 answersHow is the Siemens CQD125 circuit breaker mounted?
The CQD125 is designed for DIN rail mounting. It snaps directly onto a standard 35mm DIN rail, making it ideal for OEM control panels and DIN rail enclosures.
What is the difference between Siemens CQD and BQD circuit breakers?
Both share the same electrical ratings and internal mechanisms, but they have different mounting styles. The CQD125 is designed for DIN rail mounting with cable-in/cable-out lugs, while the BQD frame is typically panelboard mounted.
Can the CQD125 be used in DC applications?
Yes, this 1-pole breaker is rated for up to 125VDC with an interrupting capacity of 14kAIC, making it suitable for specific direct current control circuits.
What wire sizes are compatible with the lugs on the CQD125?
The factory-installed feed-thru lugs accept 14 to 6 AWG copper conductors or 12 to 6 AWG aluminum conductors.
How does the interrupting rating of the CQD125 change based on system voltage?
The breaker provides a 65kAIC rating at 120VAC and 240VAC. When applied in 277VAC or 125VDC systems, the maximum interrupting rating is 14kAIC.
Is the Siemens CQD125 suitable for reverse feed applications?
Yes, Siemens CQD molded case circuit breakers are UL Listed for reverse feed applications, allowing power to be supplied from either the line or load side terminals.
What type of trip unit is installed in the CQD125?
It features a fixed thermal-magnetic trip unit providing Long-Time and Instantaneous (LI) protection against overloads and short circuits. The trip settings are not adjustable.
Can I use the CQD125 to replace a standard residential breaker?
No, the CQD125 is a specialized DIN rail mounted breaker for OEM panels and industrial enclosures. It will not fit into standard residential load centers that require plug-on or bolt-on breakers.
