Description
Part of the BQ series, this 30/15A quadplex circuit breaker provides an efficient way to expand electrical capacity in space-constrained panels. By fitting four poles into a two-pole footprint, it reduces the need for costly subpanels. This unit is specifically designed to mount into Eaton and Cutler-Hammer Type BR load centers via a standard plug-on connection. It features a 10kAIC interrupt rating at 120/240VAC, HACR certification, and reliable thermal-magnetic protection for branch circuits.Specifications

Product FAQs
8 answersWhich load centers are approved for the BQ230215 quadplex breaker?
It is UL listed for Eaton, Cutler-Hammer, and legacy Bryant Type BR load centers. The panel must be designed to accept CTL (Circuit Total Limiting) breakers, meaning the busbar must have the appropriate notches for the rejection clip.
How many panel spaces does this quadplex breaker occupy?
The BQ230215 requires two standard 1-inch spaces in a Type BR load center. It provides four poles of protection, effectively doubling the circuit capacity in those two spaces.
What is the exact circuit layout for the BQ230215?
This quadplex unit contains one 2-pole 30A circuit and one 2-pole 15A circuit. It features an independent trip design, meaning a fault on the 30A circuit will not trip the 15A circuit, and vice versa.
Why does the BQ230215 have a rejection tab?
The rejection tab is a CTL (Circuit Total Limiting) feature that prevents the breaker from being installed in panel slots not rated for tandem or quadplex breakers. This ensures the panel's maximum circuit capacity is not exceeded.
Is the BQ230215 rated for HVAC equipment?
Yes, all Eaton Type BQ quadplex circuit breakers are HACR rated, making them suitable for heating, air conditioning, and refrigeration motor loads.
Can I install this Eaton BR quad breaker in a Siemens or Square D Homeline panel?
No. While the 1-inch plug-on design may look similar, the BQ230215 is only UL listed for Eaton/Cutler-Hammer Type BR panels. Mixing brands voids the UL listing and violates NEC requirements.
Will this replace an older Bryant quadplex breaker?
Yes. Eaton acquired Bryant and integrated their designs into the BR line. The BQ230215 is the direct, UL listed replacement for legacy Bryant quad breakers with matching 30A/15A configurations.
Are the 15A and 30A circuits internally tied together?
No. The BQ230215 utilizes an independent trip mechanism. The 15A two-pole circuit and the 30A two-pole circuit operate separately, so an overload on one will not disconnect power to the other.
