Product FAQs
7 answersWhat is the difference between the Siemens CQD335 and BQD335?
The primary difference is the mounting style. The CQD335 is designed for DIN rail mounting in OEM control panels and enclosures, while the BQD335 is a bolt-on breaker designed for installation in Siemens panelboards.
Is the CQD335 suitable for reverse feed applications?
Yes, Siemens CQD circuit breakers are UL Listed for reverse feed applications. This allows the line and load connections to be wired to either the top or bottom terminals.
Is this breaker HACR rated?
Yes, the Siemens CQD335 is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
Does the CQD335 provide GFCI or AFCI protection?
No, this is a standard thermal-magnetic circuit breaker that provides overload and short-circuit protection. It does not include ground-fault or arc-fault protection capabilities.
Can I add a shunt trip or auxiliary switch to the CQD335?
Yes, Siemens offers field-installable internal accessories for multi-pole CQD breakers. Options like shunt trips, auxiliary switches, and alarm switches can be attached to the left side of the breaker.
Can the CQD335 be used in DC power systems?
Yes, in addition to its AC ratings, this breaker is rated for use in direct current applications with an interrupting capacity of 14kA at 125/250VDC.
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 designed for use on solid-grounded wye systems rated up to 480Y/277VAC.
