Product FAQs
8 answersWhat load centers are compatible with the BQ2202120 quadplex breaker?
This breaker is designed for use in Eaton BR, Bryant, Westinghouse, and Challenger load centers. The panel must be designed to accept quadplex breakers, which typically requires notched bus stabs for Class CTL compliance.
How many panel spaces does this quadplex breaker require?
The BQ2202120 requires two standard 1-inch spaces in the panel to provide four independent 20-amp poles, maximizing panel density without upgrading the enclosure.
What does independent trip mean for this BQ series breaker?
As an independent trip breaker, each pole trips independently during a fault. Unlike common trip breakers, a fault on one pole will not automatically trip the adjacent pole, even if they share a handle tie.
Does this breaker feature a rejection clip for Class CTL panels?
Yes, this is a Class CTL plug-on breaker that includes a rejection tab. It can only be installed in panel spaces specifically designed to accept tandem or quadplex breakers.
Can I install this breaker in an older non-CTL load center?
No, because it features a Class CTL rejection tab, it is not compatible with older non-CTL load centers that lack the corresponding notched bus stabs.
Can I use this to replace older Bryant or Westinghouse quad breakers?
Yes, Eaton BR series breakers are the direct, UL-listed replacements for legacy Bryant BR, Westinghouse Type BR, and Challenger load centers.
Is the BQ2202120 rated for HACR applications?
Yes, Eaton BQ quadplex circuit breakers carry a listing for Heating, Air Conditioning, and Refrigeration (HACR) applications.
Does this breaker provide Arc Fault or Ground Fault protection?
No, this is a standard thermal-magnetic breaker providing overload and short-circuit protection. It does not include AFCI or GFCI circuitry.
