WEBDIN 43 671 specifies the continuous currents for busbars at an ambient temperature of 35°C and an average busbar temperature of 65°C. With the aid of a correction factor (k2), the continuous currents specified in the follow-ing table may be adjusted to alternative oper-ating temperatures.
Current load capacity of copper and aluminium busbars
WEBJan 23, 2020 · A diagram of these temperatures allowing to determine the correction factor for copper busbars is given in DIN 43671 standard. It enables us to determine the cross-section of a copper busbar for the ambient temperature of 0°C to 60°C and the operating temperature up to 125°C – figure 1.
WEBThe connection unit can be used as a guide to make punching the 5- and 10-mm thick bars easier. Spacing two or three prepunched bars becomes simple using the connection unit as a guide. Simple and quick derivations with cables up to 16 and/or 25 sq.mm (terminal lug) which can be used up to 400 A.
WEBCurrent-carrying capacity values for flat bars acc. to DIN 43671 According to DIN 43671, current-carrying capacity values for flat bars are defined as 35 °C ambient temperature and 65 °C bus-bar temperature. If a higher bar temperature than 65 °C is possible, the busbars can be operated with higher current values according to the
