Product Description

FZN58-12 Series indoor AC high voltage vacuum load switch, load switch - fuse combinations
 
1. Product Description
        FZN58-12/T630-20 Type indoor AC high voltage vacuum load switch and FZR N58-12 / T125 -31.5 load switch - fuse combination is suitable for 50Hz, rated voltage of 10kV network. May be breaking the load current, overload current and short circuit current; phase also has a protective effect, especially suitable for oil-free, no maintenance and long cycle operation requires frequent the place, and widely used in RMU, box substations.
        This product has a high-level, low maintenance, compact, and is suitable for use on city networks and other large projects.

3. Structure Introduction
        Vacuum load switch fitted solid seal vacuum pole, spindle, opening spring, rubber cushion and other components installed in the undercarriage, the undercarriage back has mounting holes for hanging with a load switch, spindle insulated rod, crank arm with vacuum interrupter movable guide rod connection. Mechanism mounted on the base chassis side, the side that match your switch is installed in the cabinet.
        By a combination of electrical FZN58- 12 vacuum load switches, fuses, frame, seat and contact trip device and other components, frame made of aluminum coated zinc plate bending assembled, the fuse with a maximum current up to 125A. Electric hand can operate dual load switch. Three-phase fuse arranged longitudinally.
        This product has the lack of protection function, when the short-circuit current or load current flows through the main circuit in which any one or more phases of the fuse is blown, the impactor motion, energy output and rapid impact load interlock switch, the load switches gate.
