Product FAQs
8 answersWhat panelboards are compatible with the CQD315?
The CQD315 is designed for use in DIN rail enclosures and Siemens P1, P2, and P3 panelboards. It mounts independently on a standard 35mm DIN rail or can be bolted directly to a surface.
What is the difference between Siemens BQD and CQD circuit breakers?
Both are 1 inch wide per pole and share similar electrical ratings, but they have different mounting styles. BQD breakers are panel mount or bolt-on for panelboards, while CQD breakers like the CQD315 are designed for DIN rail mounting or surface mounting.
Can the CQD315 be used in DC applications?
Yes, the CQD315 is rated for DC applications up to 125/250VDC with an interrupting rating of 14kAIC.
Is the CQD315 suitable for reverse feed applications?
Yes, Siemens CQD breakers are UL Listed for reverse feed applications.
What wire sizes do the lugs on the CQD315 accept?
The feed-thru lugs on the 15A CQD315 accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire.
Is the CQD315 HACR rated?
Yes, Siemens CQD breakers in the 15A to 100A range are HACR marked for use with heating, air conditioning, and refrigeration equipment.
Can this breaker be used on a 3-phase delta 480V grounded B phase system?
No, Siemens CQD breakers are not suitable for 3-phase delta 480V AC grounded B phase applications. They are rated for 480Y/277V solid-grounded wye systems.
Can auxiliary switches or shunt trips be added to the CQD315?
Yes, shunt trips, auxiliary switches, and alarm switches can be field installed. These add-on modules attach to the left side of the circuit breaker.
