Residual current protection for charging devices ------------------------------------------------------ -mobility is booming, and opening up a profitable future market -------------------- E for electrical specialists: the higher the number of electric cars on the roads, the greater the need for charging points. Residual current protection for charging pedestals, wall boxes and similar devices can be problematic, but Doepke's residual current circuit-breakers for electric vehicles (EV design) offer a problem-free solution. Reliable protection for e-mobility ------ mooth DC residual currents...

Doepke's residual current circuit-breakers (EV design) are available in Type A and Type F versions. The DFS 4 A EV detects sinusoidal AC and pulsating DC residual currents, regardless of the mains voltage. The DFS 4 F EV also detects residual currents with mixed frequencies. Electronic wiring and power electronics are required in electric vehicles for charging purposes. In the event of a fault, these can give rise to smooth DC residual currents and residual currents with mixed frequencies. The DFS 4 F EV is also short-time delayed and has increased surge current strength. This significantly...

------------------------------------------------------ esign: The right combination makes a difference -------------------- D Case 1 ----------------------------------------- he charging device is operated at an existing socket protected -------------------- T with a Type A residual current circuit-breaker. The standard requires protection against smooth DC residual currents above 6 mA. This protection is guaranteed by DFS 4 EV.

Case 2 ---------------------------------------- he charging device has a fixed connection. In this case --------------------- T the installation of a DFS 4 EV is sufficient. It ensures complete protection against residual currents. There is no need for an upstream residual current circuit-breaker.

Case 3 ---------------------------------------- witch-off times are subject to stricter rules in this instance. -------------------- S Charging devices with a fixed connection therefore require an upstream residual current circuit-breaker. The downstream DFS 4 EV guarantees the protective function of upstream residual current circuit-breakers even in the event of smooth DC residual currents above 6 mA

Case 4 ---------------------------------------- f several charging devices are placed downstream of a residual --------------------- I current circuit-breaker, the latter must be AC-DC sensitive as the smooth DC residual currents can add up. The EV design provides each charge plug socket with its own residual current circuit-breaker. Complete solution for charging points -- lay it safe with Doepke's residual current circuit-breakers (EV -- P design): the DFS 4 EV devices provide a comprehensive guarantee of the required protection for charging points. Their active additional function means...
