HICO America now supplies the North American market with SF6 gas circuit breakers with voltage ratings from 145kV to 550 kV and short circuit ratings up to 63 kA.


 

HICO gas circuit breakers are designed using the same powerful design tools and techniques that the industry has already come to expect from HICO power transformers. Computer analysis is used to verify all designs electrically, mechanically, and thermally.

 

HICO SF6 gas circuit breakers meet the most stringent design standards and comply with IEEE, ANSI, and ASME standards.

HICO circuit breaker and GIS manufacturing is supported by clean room assembly.
