Product FAQs
7 answersCan the Siemens CQD235 be reverse fed?
Yes, Siemens CQD series circuit breakers are UL Listed for reverse feed applications.
What enclosures is the CQD235 compatible with?
The CQD235 is designed for use in DIN rail enclosures. It mounts independently on a customer-supplied DIN rail or can be bolted directly to a flat surface.
Is the Siemens CQD235 HACR rated?
Yes, Siemens CQD breakers in the 15-100A range, including the 35A CQD235, are HACR marked for use with heating, air conditioning, and refrigeration equipment.
How is the CQD235 wired for 250VDC applications?
The CQD235 is rated for 125/250VDC. When applied on 250VDC systems, this two-pole breaker is generally wired with one pole on each leg of the direct current supply circuit.
What temperature rating is required for conductors connected to the CQD235?
Because it has a rated ampacity of 100A or less, the CQD235 must be connected using 60C or 75C rated wire. The terminal connectors are UL listed for 60/75C copper or aluminum conductors.
Where are add-on accessories installed on the CQD235?
Accessories such as shunt trips, auxiliary switches, and alarm switches are contained within an add-on module that attaches exclusively to the left side of the CQD frame.
What is the difference between Siemens BQD and CQD series breakers?
Both series feature a 1-inch pole width and share similar electrical ratings, but they utilize different mounting methods. BQD breakers are designed for panelboard mounting, whereas CQD breakers like the CQD235 are built for DIN rail or surface mounting.
