Description
Built for circuit protection, the Siemens BQD6115 is a 1-pole molded case circuit breaker rated 15A at 347VAC. It has a CSA interrupting rating of 10kA at 347VAC and standard protection. This BQD series breaker uses a BQD-Frame and bolt-on mounting. Its thermal magnetic trip provides long-time and instantaneous protection (LI). The wire range is 14-6 AWG copper and 12-6 AWG aluminum.Specifications

Product FAQs
7 answersHow should I use the Siemens BQD6115's 15A rating when selecting a breaker?
The Siemens BQD6115 is rated 15A. Use that current rating when coordinating the circuit load, conductor ampacity and required overcurrent protection; it is not an adjustable current setting.
What circuit voltage and pole arrangement is the Siemens BQD6115 rated for?
The Siemens BQD6115 is rated 347VAC with one pole for single-phase service. Select it where the circuit voltage is within that rating and the protection arrangement calls for interrupting one pole.
How does the interrupting rating affect where I can install the Siemens BQD6115?
The Siemens BQD6115 has a CSA interrupting rating of 10kA at 347VAC. The available fault current at the installation point must not exceed that rating, so check it separately from the breaker's 15A current rating.
How does the Siemens BQD6115 trip, and can its trip settings be adjusted?
The Siemens BQD6115 uses thermal-magnetic protection with an LI trip function. The thermal element responds to sustained overloads, while the magnetic element responds rapidly to high fault currents. Both settings are fixed, so choose it for applications that do not require field-adjustable trip settings.
What mounting and terminal connection does the Siemens BQD6115 use?
The Siemens BQD6115 uses bolt-on mounting and a stud/tapped pad terminal connection. Installation involves a bolted mounting attachment and a fastened electrical termination, rather than a plug-in mounting connection.
How does the conductor temperature rating affect wire selection for the Siemens BQD6115?
The Siemens BQD6115 has a 60/75 °C conductor temperature rating. Apply the appropriate temperature-based conductor ampacity when sizing the circuit conductors; insulation temperature alone should not determine the ampacity used at the termination.
What operating temperature should I consider when selecting the Siemens BQD6115?
The Siemens BQD6115 has a 40 °C operating temperature rating. Evaluate the temperature at the installation location against this rating when selecting the breaker.
