Over deze norm
IEC 62752 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 standard 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 standard • has a control pilot function controller in accordance with IEC TS 62763; • checks supply conditions and prevents charging in case of supply faults under specified conditions; • may have a switched protective conductor. These IC-CPDs are intended for use in TN-, and TT-systems. The use of IC-CPDs in IT systems may be limited. Residual currents with frequencies different from the rated frequency, d.c. residual currents and specific environmental situation are considered. This standard 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 standard is applicable to IC-CPDs for single-phase circuits not exceeding 250 V or multiphase circuits not exceeding 480 V, their maximum rated current being 32 A.
