Product FAQs
5 answersWhat is the difference between the Siemens BQ2B080 and the BQ2B080H?
The BQ2B080 has a standard interrupting rating of 10kAIC at 120/240VAC. The BQ2B080H features a high-interrupting capacity of 22kAIC at 120/240VAC. Both share the same physical dimensions and bolt-on mounting style.
Which panelboards are compatible with the BQ2B080H breaker?
This breaker is designed for use in Siemens modular meter centers and legacy ITE panelboards that accept bolt-on BQ frame breakers.
Is the Siemens BQ2B080H HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires motor branch circuit protection.
Do I need to purchase load lugs separately for the BQ2B080H?
No, this breaker comes with factory-installed load side lugs. They accept 8 to 1 AWG copper conductors or 6 to 1/0 AWG aluminum conductors.
How does the trip mechanism operate on the BQ2B080H?
It utilizes a thermal-magnetic trip unit with fixed long-time and instantaneous functions. The 2-pole design includes an internal common trip, ensuring both legs disconnect simultaneously during a fault to protect 240V loads from single-phasing.
