VSB STATION BREAKERS

The most reliable, safe and robust Air-Insulated outdoor breaker

VSB Station Breakers

Design for the North American conditions, CO7 Technologies VSB indoor and outdoor vacuum air insulated substation circuit breakers combine the proven medium voltage circuit breaker technology from Schneider Electric and CO7 with our industry-leading design. Engineered and built in our facilities in Montreal (QC) and Sherbrooke, Canada, the VSB Station Breaker meets or exceeds relevant IEEE/ANSI standards for indoor and outdoor circuit breakers at 27kV, up to 2500A.
