Product FAQs

8 answers
When should I select the Siemens BQ2B010 for a 10A circuit?

Its rated current is 10A. Select it when the circuit design calls for a 10A breaker, coordinating that selection with the load and conductor protection requirements.

What voltage and phase should I use this breaker for?

This is a 2-pole breaker rated 120/240VAC for single-phase use. Match the circuit voltage and pole requirements to these ratings when selecting it.

How do I evaluate the 10kA interrupting rating?

The interrupting rating is 10kA at 120/240VAC. Compare the available fault current at the installation point with this rating; it must not exceed the breaker's interrupting capacity.

How does the thermal-magnetic trip work, and can I adjust it?

The thermal element provides long-time overload protection, while the magnetic element provides instantaneous response to short-circuit current. Both trip settings are fixed, so select the breaker based on its preset protection rather than field adjustment.

What does bolt-on mounting mean for installation?

Bolt-on mounting uses a bolted connection to secure the breaker. Plan for tool access to the mounting hardware during installation.

What conductor sizes should I plan for?

The wire limits are AWG 16 Cu minimum and AWG 10 maximum. Check conductor size against these limits while also meeting the circuit's load and conductor protection requirements.

How is the outgoing circuit connected?

The outgoing circuit connects through a load-side lug. Plan to terminate the load conductor at that lug and select its size within the breaker's wire limits.

What dimensions should I account for in the installation layout?

The breaker measures 2 in high, 3 in wide and 4 in deep. Use these dimensions to account for the breaker body in the installation layout.
