Fzn25-12D 12kv 630A Load Break Switch

PRODUCT DETAILSFZN25/FZRN25 type vacuum load switch Description:        FZN25/FZRN25 type vacuum load switch and composite apparatus, suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment. for load control and short circuit protection use, load switch open and close the closed-loop current, no-load transformer and cable charging current, composite apparatus can break any current till rated short circuit current. Adopt the straight move or isolating fracture and vacuum interrupter linkage. With the function of manual and electric operation.ZN25, FZRN25 special transmission structure design, arc extinguish chamber only withstand voltage in the moment of closing and breaking, small size, low price.ZN25, FZRN25 can realize isolation fracture and arc extinguish chamber fracture disposable operating FZN25, FZRN25 has a grounding switch mutual linkage grounding valve between the static contact and movable conductive cylinder, ensures safety and convenient maintenance. TECHNICAL PARAMETER  The technical parameters of the form are for reference only. Customized products can consult online customer service!No.project unitsparameterFZN25-12D/T630-20FZRN25-12D/T125-31.51The rated voltagekV122Rated frequencyHZ503Rated currentA6301254Rated insulation levelVoltage withstand 1min power frequencykVArc extinguishing chamber fracture 30;To the ground, interphase 42;Isolation fracture 48Lightning shock withstand voltagekVTo the ground, phase 75;Isolation fracture 855Rated dynamic stability current (peak)kA50-64S heat stabilized currentkA20-7Rated active load breaking currentA6301258Rated closed-loop breaking currentA6301259Rated cable charging break currentA101010Turn off the no-load transformer capacityKVA1250125011Rated short circuit breaking currentkA-31.512Rated transfer current, rated transfer currentA-200013Fuse type -SDLAJ-12 SFLAJ-1214Impactor outputs energyJ-2-5(medium)15Rated short circuit closing currentkA5016Ground switch rated dynamic stable currentkA50172S thermal stability current of ground switchkA2018Rated voltage of the auxiliary circuitVAC/CD:220/11019Mechanical lifetime10000THE USE OF CONDITIONS1.Ambient air temperature: upper limit +40ºC, lower limit-25ºC (allow storage at -30ºC), 24h average value is not higher than +35ºC2.Altitude: no more than 1000m3.Relative humidity: daily average value is not greater than 95%, the monthly average is not greater than 90%4.Earthquake intensity: do not exceed 8 degree5.The surrounding air is not corrosive and flammable gas, steam and other significant pollution6.No regular violent vibration7.Contamination grade: Il classRELATED PRODUCTS  COMPANY INFORMATION    Zhejiang ZheGui Electric Co., Ltd established in 2013.
