Title
When dimensioning the line circuit breaker, the increased ambient temperatures in the distribution 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.

DC leakage protection is provided by means of electrical galvanic separation and an internal Insulation
Monitor Device.
Eaton recommends that DC EV chargers installed in a TT system are equipped with an RCD upstream in
accordance with IEC 60364-7-722.
Eaton recommends that DC EV chargers installed in a TN system where a fire hazard is present are
equipped with an RCD upstream in accordance with IEC 60364-7-722.
Eaton’s support teams can help with the selection of the proper RCD to be used.
In case of connection in TN-C-S networks, earth rods must be used.
It is not possible to install the unit in an IT grid configuration.
Always refer to local regulations which may differ from and can supersede the international regulations
listed here.
The circuit breakers and the power cable minimal cross-sections shall be over-dimensioned to ensure the
functionality of the EV charger at higher temperatures.
During installation, other important issues such as selection of a suitable line circuit breaker must be
considered:
•
The temperature where the circuit breaker is located does not exceed its reference value.
•
The circuit breaker can withstand the maximum current without tripping under the worst temperature
conditions.
Refer to local standards and regulations for further details.
