Load break Switch

Description

FN****2 Series Indoor H.V. Load Switch Summary It is a three phase H.V switch equipment of *2KV. *0Hz for breaking or closing load current. no-load transformer cable charging current and closing short-circuit current. The load switch with earth switch can bear short-circuit current. It is made up of FN****2D load switch and S□LAJ**2(XRNT□**0) H.V current-limiting fuse box. It can break any current, load switch breaking working current and fuse box breaking short-circuit current. jointly breaking any current between short-circuit current. meantime. fuse box make the switch off of with the striker. Application It is used in the ring network city distribution and industrial equipment of *2KV and three-phase AC *0Hz to cortrol load and short-circuit. because the switch with fuse protecting transformer etc more reliably than circuit breaker. It is especialy suitable for ring network clouble radial distribution and package substation. Standard a. GB******0 <<***3KV AC H.V load switch>>. B. GBXXXX-XX <<AC H.V load switch with fuse box>>(the same IEC*******0). C. GB******9 <<AC H.V isolate switch and earth switch>>. Service condition A. The ambient air temperature: Max.: *0 ℃. Min: **0 ℃. B. The altitude ≤ ***0m. C. The relatire humidity of air. daily average ≤ *0%. monthly average ≤ *5%. D. The ambient air should not be obviously polluted by corrosivity or the flammability gas and geam. etc. E. Without frequent shake. F. Enviroment degree: grade Ⅱ. If requirements are not mentioned above, users can fix them with the manufacturer.
