Title
When dimensioning the line circuit breaker, the increased ambient temperatures in the control cabinet
must also be considered. Under certain circumstances, this can make a reduction of the charging current
specification necessary in order to increase the system availability.
The nominal current must be determined in accordance with the type plate data in coordination with the
desired charging power and the supply line.
Figure 18. xChargeIn DC 22 charging station wiring
In accordance with IEC 60364-7-722 a RCD is not required, unless in TT and TN systems in areas where
a fire hazard is present. There, a RCD with rated residual current of <= 300 mA shall be used for fire
protection, in accordance with IEC 60364-4-42 and local standards.
The circuit breakers and the power cable minimal cross-sections are overvalued to ensure the functionality
of the charging station with higher temperatures.
During installation, other important issues such as “cascading” of RCDs and selection of a suitable line
circuit breaker must be considered.
It is permitted to supply the 32 A terminal, under the following conditions:
•
If the temperature where the circuit breaker is located does not exceed its reference value.
•
If the circuit breaker can withstand the maximum current without tripping under the worst temperature
conditions.
•
Please refer to local standards for further details.
