| Online Prefixes: Westinghouse Breakers 31
Prefixes for new Westinghouse [now Cutler-Hammer] circuit breakers are listed in Aaker.com's online database.
Note: some of these Prefixes were formerly sold under the "Westinghouse" brand
name. However, since Eaton Corp purchased the Westinghouse circuit breaker
business several years ago, it now sells both the Cutler-Hammer and the
former Westinghouse breakers under the "Cutler-Hammer" brand
name. For each Prefix the following tables shows the poles, amps, ac voltage and frame size for the Westinghouse [now Cutler-Hammer] circuit breakers in our online database. The AIC [Average Interrupting Capacity] is read in conjunction with the AC Voltages. For example, the "FDB" prefix shows AICs of 18/14/14 kA and AC Voltages of 240/480/600 vac. The AICs are read 18kA @ 240vac, 14kA @ 480vac and 14kA @ 600vac. |
