BS EN IEC 62752:2024

1 Scope This International Standard applies to in-cable control and protection devices (IC-CPDs) for mode 2 charging of electric road vehicles, hereafter referred to as "IC-CPD", including control and safety functions. This document applies to portable devices performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. The IC-CPD according to this document

provides a control pilot function in accordance with IEC 61851‑1:2017, Annex A ;
checks supply conditions and prevents charging in the event of supply faults under specified conditions;
can have a switched protective conductor.

Residual currents with frequencies different from the rated frequency, DC residual currents and specific environmental situations are considered. This document is applicable to IC-CPDs performing the safety and control functions as required in IEC 61851‑1 for mode 2 charging of electric vehicles. This document is applicable to IC-CPDs for single-phase circuits not exceeding 250 V or multi-phase circuits n...
