Home / The secondary distribution box can be equipped with a residual current device RCD
The residual current device consists principally of a core and a current-sensing relay. ABB offers a total ev charging solution from compact, high quality AC wall boxes, reliable DC fast charging stations with robust connectivity, to innovative on-demand electric bus charging systems, we deploy infrastructure that meet the needs of the next generation of smarter mobility. More and more laws, guidelines and standards have to be followed when constructing electrical systems, including the DIN VDE 0100-410 standard, which requires a residual current device (RCD) for final circuits of up to 32 amperes. This safety precaution takes effect when the basic protection ceases to be effective and prevents.
