SF6 Breakers joints abb

High-voltage circuit-breaker for 6 kV is intended for operative and accidental switching in the networks of three-phase alternate current composed of sf6-gas -gas-insulated switchgears (GIS). Thus, it is produced to be used in all GIS types, including updating of old series GIS to change dated types of circuit-breakers.
