The FVB series vacuum circuit breaker can use on overhead distribution lines as well as
distribution substation applications for all voltage classes 11kV up to 38kV at 50/60HZ power
system. And its rated current can reach 1600A.
The FVB series vacuum circuit breaker integrates the functions of control, protection,
measurement,communication,fault detection,on-line monitoring of closing or opening.
