Protective devices

The tasks described in this section may only be carried out by a qualified electrician.

The following conditions must be met when installing the protective devices in the upstream electrical installation:

Residual current circuit breaker

  • National regulations must be observed (e.g. IEC 60364‑7‑722 (in Germany DIN VDE 0100‑722)).
  • A differential current sensor for DC residual current monitoring > 6 mA with tripping characteristics in accordance with IEC 62752 is integrated in the product.
  • The product must be protected by a type B residual current circuit breaker if it is subject to the scope of IEC 60364-7-722:2018.
  • Each charging point that is subject to the provisions of IEC 60364-7-722:2018 must be protected by a dedicated type B residual current device.
  • The product must be protected by at least one type A residual current circuit breaker if it is subject to the scope of HD 60364-7-722:2016.
  • Within the scope of HD 60364-7-722: 2016, each charging point must be individually protected with at least one type A residual current device.
  • No other circuits may be connected to the residual current circuit breakers.

Supply line fuse (e.g. miniature circuit breaker, NH fuse)

  • National regulations must be observed (e.g. IEC 60364‑7‑722 (in Germany DIN VDE 0100‑722)).
  • The fuse for the supply line must be designed for the product, taking account, among other considerations, of the rating plate, the required charging power and the supply line (line length, cable cross-section, number of outer conductors, selectivity).
  • The following applies for : The rated current of the fuse for the supply line must not exceed 20 A (with C characteristics).
  • The following applies for : The rated current of the fuse for the supply line must not exceed 40 A (with C characteristics).

Shunt release

Only valid for the product variants with a switching output for controlling an external shunt release.

  1. Check whether a shunt release is legally prescribed in the country of use.

Intended use

  • The shunt release must be positioned next to the line circuit breaker.
  • The shunt release and the line circuit breaker must be compatible with each other.
