Description
Maximizing available slots in crowded panels, the Eaton BRD220240 delivers two 20A single-pole circuits and one 40A double-pole circuit in a two-pole footprint. This miniature breaker is perfect for adding new residential branch circuits. As a non-CTL component without a rejection tab, it plugs into older Cutler-Hammer and Eaton Type BR load centers. It replaces the discontinued BQ220240. The 40A inner poles offer common trip protection, while the 20A outer poles trip independently.Specifications

Product FAQs
6 answersWhat panels accept the BRD220240 quad breaker?
This non-CTL breaker is designed for older Eaton, Cutler-Hammer, and Bryant Type BR load centers that do not utilize rejection tabs. It is typically used to maximize circuit density in legacy panels.
Is the BRD220240 a direct replacement for the BQ220240?
Yes, the BRD220240 is the exact manufacturer replacement for the discontinued Cutler-Hammer BQ220240 quadplex breaker.
How are the trip mechanisms configured on the inner and outer poles?
The 40A inner poles utilize a common trip mechanism for 240V loads. The two 20A outer poles feature independent trip mechanisms, allowing them to protect separate 120V branch circuits without tripping each other.
How much panel space is required to install this quadplex breaker?
The BRD220240 requires two standard 1-inch spaces in a Type BR load center. It provides the equivalent of two single-pole breakers and one double-pole breaker within that two-pole footprint.
Can I install the BRD220240 in a modern CTL panel?
Because the BRD220240 is a non-CTL breaker without a rejection tab, it is intended for older panels manufactured before Circuit Total Limiting (CTL) standards were implemented. Modern CTL panels require breakers with rejection features to prevent exceeding the panel's designed circuit capacity.
What does the LI trip function indicate on this breaker?
The LI designation means this breaker uses standard thermal-magnetic trip technology. The long-time (L) function provides thermal protection against mild overloads, while the instantaneous (I) function offers magnetic protection against severe short circuits.
