This International Standard applies to in-cable control and protection devices (IC-CPDs) for 466 mode 2 charging of electric road vehicles, hereafter referred to as IC-CPD including control and 467 safety functions. 468 This standard applies to portable devices performing simultaneously the func tions of detection 469 of the residual current, of comparison of the value of this current with the residual operating 470 value and of opening of the protected circuit when the residual current exceeds this value. 471 The IC-CPD according to this standard 472 • has a control pilot function controller in accordance with IEC 61851-1:2017, Annex A; 473 • checks supply conditions and prevents charging in case of supply faults under specified 474 conditions; 475 • may have a switched protective conductor. 476 Residual currents with frequencies different from the rated frequency, DC residual currents and 477 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 multi481 phase circuits not exceeding 480 V, their maximum rated current being 32 A. This standard is applicable to IC-CPDs to be used in AC circuits only, with preferred values of rated frequency 50 Hz, 60 Hz or 50/60 Hz. IC-CPDs according to this standard are not intended to be used to supply electric energy towards the connected grid.
