Oil Circuit Breaker Support Capabilities
As of October 1, 2008, our U.S. business is called Siemens Energy, Inc.
Siemens and Allis-Chalmers manufactured oil circuit breakers as early as the 1920s under the model names BZO, SDO, TDO, FZO, & OZ rated from 15 - 242 kV. In the late 1970s, Siemens purchased the rights to the Allis-Chalmers design and continued to manufacture them until 1996.
