Products FZN25-12RD / T125-31.5, FZN25-12R / T125-31.5, FZN25-12 / T630-20, FZN25-12D / T630-20 other models for users to choose products with manual operation and AC and DC operating power The two forms of electric operation, easy to implement power system 'three shake' requirements. These models are left to operate, the right to operate, suits, flip, users can choose according to their needs. . . Can also be customized lengthened. . . FZN25, FZRN25 vacuum load switch fuse combination, suitable for AC 50Hz ring network or terminal power supply and industrial electrical equipment, as a charge control and short circuit protection, load switching division, closed-loop current, no-load transformer and cable electrical charge. Can be any combination of electrical current until breaking rated short-circuit current. Using direct-acting isolation clearance and vacuum arc chamber linkage. With manual and electric functions. Unique transmission design, interrupter only withstand high pressure in the closing moment and breaking, so the small size and light weight. Between static contact and moving contact with a flashlight guide each other linkage grounding grounding switch valve, both to ensure the safe and convenient maintenance. The main technical parameters: Rated voltage: 12KV Rated current: 630A, rated insulation level: 1min power frequency withstand voltage - interrupter fracture 30KV; on the ground, white 42kv; isolated fracture 48KV. Lightning impulse withstand voltage - to earth, white 75KV; isolated fracture 85KV Rated dynamic stability current (peak): 50KA 4s thermal current: 20KA rated active load breaking current: 630A Rated breaking current loop: 630A rated cable charging breaking current : 10A breaking load transformer capacity: 1250KVA rated short-circuit current: 50KA Auxiliary circuit Rated voltage: AC / DC220V, 110V Mechanical life: 10000 Rated voltage: 12KV Rated current: 125A, rated insulation level: 1min power frequency withstand voltage - interrupter fracture 30KV; on the ground, white 42kv; isolated fracture 48KV. Lightning impulse withstand voltage - to earth, white 75KV; isolated fracture 85KV Rated dynamic stability current (peak): 50KA 4s thermal current: 20KA rated active load breaking current: 125A Rated breaking current loop: 125A rated cable charging breaking current : 10A breaking load transformer capacity: 1250KVA rated short-circuit current: 50KA Auxiliary circuit Rated voltage: AC / DC220V, 110V Mechanical life: 10000
