Challenger CF3125 Molded Case Circuit Breaker

Challenger CF3125 Molded Case Circuit Breaker is a 3-pole device rated for 125 A at 600 V AC, part of Challenger’s CF series of molded-case breakers. It delivers 35 kA interrupting capacity at 480 V and uses long-time and instantaneous trip functions to protect feeders from overcurrent, with load-side lugs for straightforward connections in panel assemblies and a 40°C ambient operating rating. The CF3125 configuration represents the 3P, 125A, 600V option within the CF line, a legacy Challenger model commonly referenced in catalogs and reseller listings. Challenger brand lineage continues under Eaton’s portfolio, where Series C molded-case breakers (for example, the FD3125) mirror the same 3-pole, 125 A at 600 V class and similar trip characteristics for industrial power distribution.
