Product Description

FZN25-12 Indoor AC HV vacuum Load break switch and FZRN25-12D Indoor AC HV vacuum load break switch with assembly fuse is the controlling and protecting equipment of three-phase 50Hz, 12kv distribution system, which is widely used in the situations of industrial and mining establishiments and power distribution station of urban buildings. Combined electrical apparatus can protec transformer and other electric equipments. it is used more reliable than circuit breaker. esbecially, it can be perfectly used in terminal substation and box-type substation of urban net and rural net in order to control and protect ring net birabdial electric unit.
