Product FAQs
5 answersWhat is the difference between Siemens CQD and BQD circuit breakers?
While both share the same 1-inch per pole frame size and electrical ratings, they feature different mounting styles. The CQD325 is designed for DIN rail or surface mounting, whereas the BQD series is designed to bolt directly onto panelboard busbars.
Is the Siemens CQD325 suitable for reverse feed applications?
Yes, Siemens CQD series circuit breakers are UL Listed for reverse feed applications. This allows you to wire the incoming power to either the top or bottom terminals without affecting the breaker's protective functions.
Is this 25A CQD breaker HACR rated?
Yes, Siemens CQD breakers from 15A to 100A are HACR rated, making the CQD325 suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
Can the CQD325 be used in direct current (DC) systems?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for 125/250VDC systems, providing a 14kAIC interrupting capacity for DC applications.
How does the CQD325 mount inside Siemens P1, P2, or P3 panelboards?
While the CQD325 is primarily a DIN rail mounted breaker, it can be installed in Siemens P1, P2, and P3 panelboards using the appropriate DIN rail mounting kits or chassis adapters designed for those specific panels.
