Izolator in trepte IS4-40 (M8) power

IEK brand stepped bus insulators are intended for rigid fixing and insulation of current-conducting buses inside the electric panels, busbar bridges and other equipment. This insulator guarantees the absence of disruptive discharges between the buses and can be used in AC and DC electric equipment of 50 Hz and voltage under 1000 V. Insulator casing is made of special mechanical impact-resistant non-flammable polymer notable for its high electrical resistance ratings.Insulator casing is made of special mechanical impact-resistant non-flammable polymer notable for its high electrical resistance ratings.Number of poles: 4 Busbar distance: 41 Nominal rated voltage: 660 Withstand lightning pulse voltage: 12.0 Weight: 630 Thread length: 15 Thread size metric (M..): 8 Ambient temperature: -60...+80 Short-term withstand voltage of industrial frequency: 2.5 Breakdown voltage of industrial frequency insulation: 10.0 Bending strength: 125 Tightening torque of bus attachment screws: 10.0 Destructive torque: 50 Diameter of holes for fastening screws in buses: 9.0 Width: 164.0 Height: 150.0 Depth: 30.0 Colour: EV000233 Material: IEK_V0000465 Material quality: IEK_V0000467 Max. rated current: 600
