Circuit breakers are an essential part of the air-insulated (AIS) and gas insulated (GIS) switchgear. High voltage switchgear are mechanical switching devices that connect and break current circuits (operating and fault current) and carry the nominal current in the fault position. Siemens is a world market leader in circuit breakers that are able to meet the economical, environmental conditions in various countries. 

Siemens-Allis circuit breakers are used worldwide in a variety of industrial and commercial applications. The range of Siemens-Allis circuit breakers includes air circuit breakers and vacuum circuit breakers. Besides these, you can also find a full range of other Siemens circuit breakers almost anywhere in the world. They are trusted and used worldwide.
