Adapt to 10kV distribution lines, small and medium size substation to close load
current and break short-circuit current. According to the users' need it can be
installed with manual or electrical isolator. It can have functions of remote
control in 100m distance, automatically operation power supply, automatically
open and close swithes, as well as lightning-protection. It is actually a
full-featured modular electrical apparatus. This product is a dry type with
reasonable design, simple structure, complete functions, reliable operation,
small volume and light weight. It can meet many requirements of distribution
automation.(dropout current specification:20 kA, 16 kA, 12.5 kA)
