Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCB's). Part 1: General rules (IEC 61008-1:2010, modified)

Alkalmazási terület

This International Standard applies to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage, for household and similar uses, not incorporating overcurrent protection (hereafter referred to as RCCBs), for rated voltages not exceeding 440 V a.c. with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A, intended principally for protection against shock hazard. These devices are intended to protect persons against indirect contact, the exposed conductive parts of the installation being connected to an appropriate earth electrode. They may be used to provide protection against fire hazards due to a persistent earth fault current, without the operation of the overcurrent protective device. RCCBs having a rated residual operating current not exceeding 30 mA are also used as a means for additional protection in case of failure of the protective means against electric shock. This standard applies to 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. NOTE 1 The requirements for RCCBs are in line with the general requirements of IEC 60755. RCCBs are essentially intended to be operated by uninstructed persons and designed not to require maintenance. They may be submitted for certification purposes. NOTE 2 Installation and application rules of RCCBs are given in the IEC 60364 series. They are intended for use in an environment with pollution degree 2. They are suitable for isolation. RCCBs complying with this standard, with the exception of those with an uninterrupted neutral, are suitable for use in IT systems. Special precautions (e.g. lightning arresters) may be necessary when excessive overvoltages are likely to occur on the supply side (for example in the case of supply through overhead lines) (see IEC 60364-4-44). RCCBs of the general type are resistant to unwanted tripping including the case where surge voltages (as a result of switching transients or induced by lightning) cause loading currents in the installation without occurrence of flashover. RCCBs of type S are considered to be sufficient proof against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs. NOTE 3 Surge arresters installed downstream of the general type of RCCBs and connected in common mode may cause unwanted tripping. NOTE 4 For RCCBs having a degree of protection higher than IP20 special constructions may be required. Particular requirements are necessary for – residual current operated circuit-breakers with integral overcurrent protection (see IEC 61009-1); – RCCBs incorporated in or intended only for association with plugs and socket-outlets or with appliance couplers for household or similar general purposes; – RCCBs intended to be used at frequencies other than 50 Hz or 60 Hz. NOTE 5 For the time being, for RCCBs incorporated in, or intended only for socket-outlets or plugs, the requirements of this standard in conjunction with the requirements of IEC 60884-1 may be used as far as applicable. NOTE 6 In DK, plugs and socket-outlets shall be in accordance with the requirements of the heavy current regulations, section 107. NOTE 7 In the UK, the plug part of an RCCB shall comply with BS 1363-1 and the socket-outlet part(s) of an RCCB should comply with BS 1363-2. In the UK, the plug part and the socket-outlet part(s) of an RCCB need not comply with any IEC 60884-1 requirements. The requirements of this standard apply for normal environmental conditions (see 7.1). Additional requirements may be necessary for RCCBs used in locations having severe environmental conditions. RCCBs including batteries are not covered by this standard.
