Challenger Circuit Breakers

Challenger circuit breakers were widely used in residential and commercial electrical panels during the 1980s and 1990s. Many electricians continue to encounter Challenger load centers in homes, apartment buildings, and light commercial facilities built during that period.

The Challenger electrical distribution business was eventually acquired by Eaton, and many modern Eaton breaker designs are compatible replacements for certain Challenger panels. However, original Challenger breakers are no longer manufactured, and replacement options are often sourced through compatible Eaton breakers or tested used units.
