This document gives general requirements and tests for residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (hereafter referred to as RCCBs), for rated operational voltages not exceeding 440 V AC 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 provide fault protection (previously referred to as protection against indirect contact), the exposed conductive parts of the installation being connected to an appropriate earth electrode. They are also intended to 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 used for fault protection and additional protection in the case of failure of the protective provisions against electric shock.

This document 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 group safety publication IEC 60755.

NOTE 2   RCCBs of type AC and type A are covered by the series of standard IEC 61008. RCCBs of type F and type B are covered by IEC 62423 in conjunction with IEC 61008 series

NOTE 3  Installation and selection rules for RCCBs are given in the IEC 60364 series.

NOTE 4      Installation and application rules of RCCBs in ZA is given in SANS 10142-1

RCCBs are intended to be operated by ordinary or uninstructed persons and designed not to require maintenance.

The requirements of this document apply for standard conditions (see 7.1). Additional requirements may be necessary for RCCBs used in locations having severe environmental conditions. They are intended for use in an environment with pollution degree 2 (see 7.3).

NOTE 5 For environments with higher pollution degrees, enclosures giving the appropriate degree of protection could be used.

NOTE 6 For RCCBs having a degree of protection higher than IP20 special constructions can be required.

RCCBs are suitable for isolation.

Special precautions (e.g. surge protective devices) 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 and IEC 60364-5-53).

RCCBs, with the exception of those with an uninterrupted neutral, are suitable for use in IT systems.

RCCBs of the general type are resistant to current surges, 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 sufficiently proof against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs.

NOTE 7 Surge protective devices installed downstream of the general type of RCCBs and connected in common mode can cause unwanted tripping.

Particular requirements are necessary for RCCBs intended to be used at frequencies other than 50 Hz or 60 Hz.

For RCCBs incorporated in, or intended only for association with socket-outlets, the requirements of this document may be used, as far as applicable, in conjunction with the requirements of IEC 60884-1 or the national requirements of the country where the product is placed on the market.

NOTE 8 Residual current-operated protective devices (RCDs) incorporated in, or intended only for association with socket-outlets, can either meet IEC 62640 or this document.

NOTE 9 In DK, plugs and socket-outlets are in accordance with the requirements of the heavy current regulations section 107.

NOTE 10 In the UK, the plug part associated with a RCCB complies with BS 1363-1 and the socket-outlet(s) associated with a RCCB complies with BS 1363-2. In the UK, the plug part and the socket-outlet(s) associated with a RCCB need not comply with any IEC 60884-1 requirements.

NOTE 11   In ZA, RCCBs are knows as earth leakage switches (ELSWs).

This document does not apply to:

RCCBs the current setting of which is adjustable without a tool.

RCCBs including batteries.

This document is not intended to be used alone and it is intended to be used in conjunction with the relevant product standard IEC 61008-2-1 or IEC 61008-2-2.

This document gives general rules for residual current operated circuit‑breakers with integral overcurrent protection for household and similar uses (hereafter referred to as RCBOs), for rated operational voltages not exceeding 440 V AC with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A and rated short‑circuit capacities not exceeding 25 000 A.

These devices are intended to provide fault protection (previously referred to as protection against indirect contact), the exposed conductive parts of the installation being connected to an appropriate earth electrode and to protect against overcurrents the wiring installations of buildings and similar applications. They are also intended to be used to provide protection against fire hazards due to a persistent earth fault current, without the operation of the overcurrent protective device.

RCBOs having a rated residual operating current not exceeding 30 mA are used for fault protection and additional protection in the case of failure of the protective provisions against electric shock.

This document 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, and also of performing the function of making, carrying and breaking overcurrents under specified conditions.

NOTE 1 The requirements for RCBOs are in line with the general safety requirements of IEC 60755.

NOTE 2   RCBOs of type AC and type A are covered by the series of standard IEC 61009. RCBOs of type F and type B are covered by IEC 62423 in conjunction with IEC 61009 series.

NOTE 3  Installation and selection rules for RCBOs are given in the IEC 60364 series.”

NOTE 4 The content of this document related to operation under residual current conditions is based on
IEC 61008-1. The content of this document related to protection against overcurrents is based on IEC 60898-1.

RCBOs are intended to be operated by ordinary or uninstructed persons and designed not to require maintenance.

The requirements of this document apply for standard conditions (see 7.1). Additional requirements may be necessary for RCBOs used in locations having severe environmental conditions. They are intended for use in an environment with pollution degree 2 (see 7.3).
