Product FAQs
5 answersCan the Eaton BR2110 be installed in older Westinghouse or Challenger panels?
Yes, Eaton BR series breakers are the direct, UL-listed replacements for legacy Bryant BR, Westinghouse Type BR, and Challenger Type C load centers. Always verify your specific panel label for Type BR or Type C compatibility prior to installation.
How much panel space is required to install the BR2110?
This 2-pole miniature circuit breaker requires two adjacent 1-inch spaces on the load center bus.
Is the BR2110 suitable for use with aluminum conductors?
Yes, the box lug terminals are rated for both copper (Cu) and aluminum (Al) wire ranging from 4 AWG to 1/0 AWG. When terminating aluminum conductors, applying an approved antioxidant joint compound is recommended to ensure a reliable, long-term connection.
Does the BR2110 feature a common trip mechanism?
Yes, this 2-pole breaker features an internal common trip mechanism. If an overcurrent or short circuit fault occurs on either leg of the 240V circuit, both poles will trip simultaneously to safely disconnect power to the connected load.
How does the thermal-magnetic trip unit function on the BR2110?
The thermal-magnetic design provides dual-level protection. The thermal component offers a delayed response to continuous, low-level overloads, preventing nuisance tripping. The magnetic component provides an instantaneous trip response to severe short circuits, rapidly clearing the fault.
