Description
Built for older panelboards, the BR420 is a high-density quadplex breaker providing four 20A poles while occupying only two standard 1-inch spaces. Featuring an independent trip mechanism, it is ideal for managing multiple 120/240V circuits without a common trip. Without a Class CTL rejection tab, it is a direct fit for pre-CTL Eaton BR, Bryant, Westinghouse, and Challenger load centers. This 10 kAIC thermal-magnetic breaker delivers dependable LI protection and is HACR rated for HVAC use.Specifications

Product FAQs
6 answersIs the Eaton BR420 a CTL or Non-CTL circuit breaker?
The BR420 is a Non-CTL (Circuit Total Limiting) quadplex breaker. It does not have a rejection tab, allowing it to be installed in older Eaton, Cutler-Hammer, or Bryant load centers that lack notched bus bars.
How are the 20A circuits configured on the BR420 quad breaker?
This quadplex breaker provides two separate 240V circuits while only occupying two standard 1-inch panel spaces. It features a 2-pole 20A outer circuit and a 2-pole 20A center circuit, both utilizing independent trip mechanisms.
How much panel space is required to install the BR420?
The BR420 requires two standard 1-inch spaces in a Type BR load center. Because it is a quadplex breaker, it fits four poles of protection into the physical footprint of a standard 2-pole breaker.
Can I install the BR420 in a Siemens or Square D load center?
No. The BR420 is strictly UL-listed for use in Eaton, Cutler-Hammer, and legacy Bryant Type BR load centers. Installing it in other panel brands violates electrical code and compromises safety.
What older breaker brands does the Eaton BR420 replace?
The Eaton BR420 is a direct replacement for legacy Cutler-Hammer and Bryant BR420 quad breakers. Eaton acquired these product lines, making the modern BR series fully backward compatible with older Type BR panels.
Does the BR420 offer ground fault or arc fault protection?
No. This is a standard thermal-magnetic breaker. It provides standard overload and short-circuit protection but does not include GFCI (Ground Fault Circuit Interrupter) or AFCI (Arc Fault Circuit Interrupter) capabilities.
