give an example:
One exposed Curital bus, specification 30x10mm (E-CuF30), which is specified in DIN43671
The flow value is IN65=573A.
At 35 ° C air temperature and 85 ° C rittal bus temperature
The correction factor chart on the square section shows that the correction factor isk2=1.29。 Continuous current continues to increase due to low emissions6–10%。 The average value used in this example is 8%。 Relative to the table in DIN 43671
Given value, Rittal's specification for Curital bus 30x10mm
The rated current is:
IN85=IN65·k2+8%
=573A·1.29·1.08
IN85=800A
Continuous current of rittal bus
The width of rittal bus in indoor equipment made of E-Cu with rectangular cross section for 35 ° C air temperature and 65 ° Crittal bus temperature
The vertical or horizontal position of degrees.
Rittal PLS current load
According to the German industrial standard DIN43671, use the correction factor k2 (correction factor diagram) according to the temperature characteristics of the surrounding environment of the site
And the temperature characteristic of rittal bus to correct the reference rated current.
According to the German industrial standard DIN43671, the load value of Rittal bus of Rittal PLS is determined according to the following methods
