Insulated copper flexibars
Moflex bars are manufactured out of highly flexible copper strips either in bare or tinned version. They are insulated with high quality mechanical, electrical and self-extinguishing PVC.
Comparing with regular copper cable connections with Moflex flexibars – Moflex saves you time and money. Due to skin effect, on average 60% smaller cross section is needed compared to regular copper cable.

How to choose Moflex
ΔT = temperature rise of the Moflex conductor (°C)
T1 = internal temperature of the switchboard (°C)
T2 = temperature of the Moflex conductor (°C)
For example, In = 1000A connection
T1 = 35°C and T2 = 85°C
ΔT = T2 – T1
ΔT = 85°C – 35°C
ΔT = 50°C
Please find from the Moflex technical table
column ΔT = 50 the closest value of the 1000A.
MMC0500401 Moflex 50x1x4, 200 mm², 1027A or
MMC0630301 Moflex 63x1x3, 189 mm², 1081A.
Select the Moflex flexibar according to the
equipment terminal width.
