适用范围：This International Standard applies to portable devices for household and similar uses(hereafter referred to as portable residual current devices (PRCDs), consisting of a plug, aresidual current device (RCD) and one or more socket-outlets or a provision for connection,functionally independent of, or functionally dependent on, line voltage. They do not incorporateovercurrent protection. They are intended for single-phase circuits for rated currents notexceeding 16 A for rated voltages not exceeding 250 V a.c., or for rated current not exceeding32 A for rated voltages not exceeding 130 V a.c. to earth. They are intended to provideprotection against shock hazard in case of direct contact, in addition to the protection providedby the fixed installations for the circuit downstream.PRCDs have a rated residual operating current not exceeding 0,03 A.They ensure tripping in case of residual alternating currents and residual pulsating directcurrents, whether suddenly applied or slowly rising (see 8.15).Plugs and socket-outlets will comply with the relevant standards.This standard applies to portable devices performing simultaneously the functions of detectionof the residual current, of comparison of the value of this current with the residual operatingvalue and of opening of the protected circuit when the residual current exceeds this value.They are not intended to be used as parts of fixed installations. Their connecting means maybe plugs, socket-outlets, terminals or cords.NOTE 1 – The requirements for PRCDs are in line with the general requirements of IEC 61008-1. PRCDs areessentially intended to be operated by unskilled persons and designed not to require maintenance. They may besubmitted for certification purposes.NOTE 2 – The RCD part of the PRCD is not intended to provide isolation which may be provided by the plug.NOTE 3 – The use of an integral fuse is permitted, if necessary, for the relevant plug and socket-outlet system.NOTE 4 – In Australia and in Germany, PRCDs switching also the PE circuit are in use. Such devices are notcovered by this standard.The requirements of this standard apply for environmental conditions as defined in 7.1.Additional requirements may be necessary for PRCDs used in locations having more severeenvironmental conditions.PRCDs including batteries are not covered by this standard.The present standard does not contain additional requirements for PRCDs without earthingcontacts for which specific requirements may apply. It may, however, be used as a guide forsuch devices which are intended to be used only with Class II appliances.The present standard does not apply to PRCDs providing the additional function of detectingfaults on the supply side and avoiding the closing of the PRCD on a faulty supply circuit.
