Protection devices
Each charging station must be protected upstream by circuit breaker protection and residual current devices
required by the low voltage electrical system standard. In particular, each individual station must be protected
upstream by a Type A residual current circuit breaker 30 mA + miniature circuit breaker (the choice of device must
be suitable for the power level and the power supply of the recharging station; protection against DC leakage is
provided by the DC Leakage 6 mA device built into the products).
