適用范圍：This International Standard applies to portable devices intended for use with vehicles havingclass 1 insulation and battery powered vehicle applications having battery charging units.They have a switched protective earth (SPE) and hereafter are referred to as SPE-PRCDs.The SPE-PRCD consists of a plug, a residual current device (RCD) and a portable socketoutlet.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.In addition to the RCD function, the SPE-PRCDs address incorrect supply connectionsresulting in a hazardous live PE and/or supply failure (for example: loss of supply PE or lossof supply N). These SPE-PRCDs are intended for application only on TN and TT systems.These SPE-PRCDs will not operate if used on IT or other unearthed systems such as isolatedwinding generator or isolating transformer. These SPE-PRCDs, due to the PE effectivelybeing an open supply conductor, will not function to close the contacts on an IT system.NOTE 1 For applications where due to the supply system a SPE-PRCD cannot operate a PRCD (according toIEC 61540) may be used.SPE-PRCDs are not required to incorporate overcurrent protection.SPE-PRCDs are intended to be supplied from single-phase or two-phase circuits with ratedcurrents not exceeding 16 A for rated voltages not exceeding 250 V a.c., or with rated currentnot exceeding 32 A for rated voltages not exceeding 130 V a.c. to earth.SPE-PRCD have a rated residual operating current not exceeding 30 mA and are intended toprovide additional protection against shock hazard in case of direct contact on the circuitdownstream of the SPE-PRCD. This protection is additional to that provided by the fixedinstallations. They will not detect a direct contact of a person from line to neutral and do notsubstitute for safe installation requirements.Plugs and socket-outlets will comply with the relevant standards. The use of an integral fuseis permitted, if necessary, for the relevant plug and socket-outlet system.SPE-PRCD are not intended to be used as part of a fixed installation or permanentlyconnected to equipment. They should be connected by a plug and the outlet should be aportable socket outlet.If a SPE-PRCD of the incorrect type is used (example an LNSE instead of an LLSE) it shouldcontinue to protect.SPE-PRCDs including batteries are not covered by this standard.Additional requirements may be necessary for SPE-PRCDs used in locations having severeenvironmental conditions.
