ERIFLEX FLEXIBAR BUSBAR SELECTION AND TECHNICAL CHARACTERISTICS
SPECIFICATIONS
Temperature rise of conductor = T2 - T1 = T (K)
Ex: For a current of 630A, with: T1 = 40ºC - T2 = 90ºC
1) ∆T = 90 - 40 = 50K
2) In the 50ºK column, find the closest current value to 630A.
ERIFLEX FLEXIBAR 5x32x1 - 552650 -
160 mm2 - 640A.
3) Select ERIFLEX FLEXIBAR according to the terminal width of the
equipment being connected.
K = Kelvin degree (temperature calculated, but not measurable)
ERIFLEX FLEXIBAR in parallel
When using 2 or 3 ERIFLEX FLEXIBAR on edge in parallel for the
same phase, use the coefficient:
Ex: 5 x 32 x 1 - ∆Tº = 50 K: 640 A
2 bars in parallel > 640 A x 1,72 = 1100 A
3 bars in parallel > 640 A x 2,25 = 1440 A
Selection of FLEXIBAR Busbar
