Product FAQs

5 answers
Which Siemens panelboards accept the BQD125 circuit breaker?

This bolt-on breaker is approved for installation in Siemens Sentron Series P1, P2, P3, P4, and P5 panelboards.

Is the BQD125 circuit breaker rated for high intensity discharge lighting?

Yes, this 1-pole BQD breaker is tested and marked as HID rated, meaning it is approved for switching high intensity discharge lighting loads.

Does the BQD125 carry an HACR rating?

Yes, it is HACR marked. This confirms the breaker is certified for branch circuit protection in heating, air conditioning, and refrigeration equipment.

What is the difference between Siemens BQD and CQD circuit breakers?

Can the Siemens BQD125 be reverse fed?

Yes, Siemens BQD series circuit breakers are suitable for reverse feed applications. This allows flexibility for panel builders when routing main or subfeed wiring.
