The MaxiCharger AC Wallbox has the internal 30 mA AC and 6 mA
DC residual current detection.
In some countries, local standards may require external protection
devices. Check the local standards accordingly. External RCD+MCB
or RCBO are also recommended as below:
7.4 kW: 30 mA Type A RCBO 230 V/40 A
11 KW: 30 mA Type A RCBO 400 V/20 A
22 kW: 30 mA Type A RCBO 400 V/40 A
For EV Ready requirement:
The circuit breaker must be curve C, 40A and a short-circuit
current limited to 6000A to be sure of having a limitation of 75000
A²/s for case B and 80000 A²/s for case C. For the RCD part: meter
30 mA.
Otherwise, comply with local regulations.
NOTE
The breaker value depends on the diameter and
length of the cable, charging station rating, and the
environmental parameters (for the electrician to
decide).
