Residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBO's) -- Part 1: General rules
This International Standard applies to residual current operated circuit-breakers with integral overcurrent protection functionally independent of, or functionally dependent on, line voltage for household and similar uses (hereafter referred to as RCBOs), 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 and rated short-circuit capacities not exceeding 25 000 A for operation at 50 Hz or 60 Hz. These devices are intended to protect people 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 may 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 also used as a means for additional protection in the case of failure of the protective means against electric shock. This standard applies to devices performing simultaneously the function 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. RCBOs 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. RCBOs 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. RCBOs are suitable for isolation. RCBOs 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). This standard also applies to RCBOs obtained by the assembly of an adaptable residual current device with a circuit-breaker. The mechanical assembly shall be effected in the factory by the manufacturer, or on site, in which case the requirements of Annex G shall apply. It also applies to RCBOs having more than one rated current, provided that the means for changing from one discrete rating to another is not accessible in normal service and that the rating cannot be changed without the use of a tool. Supplementary requirements may be necessary for RCBOs of the plug-in type. Particular requirements are necessary for RCBOs incorporated in or intended only for association with plugs and socket-outlets or with appliance couplers for household and similar general purposes and if intended to be used at frequencies other than 50 Hz or 60 Hz. This standard does not apply to: - RCBOs intended to protect motors; - RCBOs the current setting of which is adjustable by means accessible to the user in normal service. The requirements of this standard apply for normal environmental conditions. Additional requirements may be necessary for RCBOs used in locations having severe environmental conditions. RCBOs including batteries are not covered by this standard. A guide for the coordination of RCBOs with fuses is given in Annex F.

Odklopniki na preostali (residualni) tok z vgrajeno nadtokovno zaščito za gospodinjsko in podobno rabo (RCBO's) - 1. del: Splošna pravila (IEC 61009-1:1996 + Corr. 2003 + A1:2002, spremenjen) (vsebuje popravek AC:2006)
Ta mednarodni standard se uporablja za odklopnike na preostali (residualni) tok z vgrajeno nadtokovno zaščito, ki so funkcionalno neodvisni ali odvisni od linijske napetosti, za gospodinjsko in podobno rabo (v nadaljnjem besedilu: RCBO), za nazivne napetosti do vključno 440 V izmenične napetosti, pri čemer nazivna frekvenca dosega 50 Hz, 60 Hz ali 50/60 Hz, nazivni tok ne presega 125 A, nazivne kratkostične zmogljivosti pa ne presegajo 25000 A med delovanjem pri 50 Hz ali 60 Hz. Te naprave so namenjene zaščiti oseb pred posrednim stikom, pri čemer so izpostavljeni prevodni deli inštalacije povezani z ustreznim ozemljilom, in zaščiti napeljav stavb in podobnih aplikacij pred nadtoki. Uporabljajo se lahko za zaščito pred požarom zaradi stalnega ozemljitvenega okvarnega toka brez naprave za nadtokovno zaščito. Tudi odklopniki na preostali (residualni) tok z vgrajeno nadtokovno zaščito (RCBO) z nazivnim preostalim operativnim tokom do vključno 30 mA se uporabljajo kot dodatna zaščita v primeru odpovedi zaščitnega sredstva pred električnim udarom. Ta standard se uporablja za naprave, ki hkrati izvajajo funkcije zaznavanja preostalega (residualnega) toka, primerjanja vrednosti tega toka s preostalo operativno vrednostjo in odprtja zaščitenega tokokroga, kadar preostali tok presega to vrednost, ter tudi funkcijo ustvarjanja, prenosa in prekinitve nadtokov pod določenimi pogoji. Odklopniki RCBO splošnega tipa se ne morejo po nesreči odklopiti, tudi kadar previsoka napetost (zaradi prehodnih preklapljanj ali udara strele) povzroči obremenilne tokove v inštalaciji brez nastanka preboja. Odklopniki RCBO tipa S naj bi v zadostni meri ščitili pred neželenim odklopom, celo kadar previsoka napetost povzroči preboj in nastane nadaljnji tok. Odklopniki RCBO so primerni za izolacijo. Odklopniki RCBO, ki so skladni s tem standardom, razen odklopnikov z neprekinjeno nevtralno točko, so primerni za uporabo v sistemih IT. Posebni zaščitni ukrepi (npr. prenapetostni odvodniki) so lahko potrebni, kadar lahko na strani dobave nastane prekomerna prenapetost (na primer v primeru dobave prek nadzemnih vodov) (glejte standard 60364-4-44). Ta standard se uporablja tudi za odklopnike RCBO, ki se pridobijo z montažo naprave s prilagodljivim preostalim (residualnim) tokom z odklopnikom. Mehansko montažo izvede proizvajalec v tovarni ali se opravi na kraju samem, v tem primeru pa se uporabljajo zahteve Dodatka G. Uporablja se tudi za odklopnike RCBO z več kot enim nazivnim tokom, če sredstvo za spreminjanje nazivnega toka ni na voljo med običajnim delovanjem in se nazivni tok ne more spremeniti brez uporabe orodja. Dodatne zahteve so lahko potrebne za vtične odklopnike RCBO. Posebne zahteve so potrebne za odklopnike RCBO, vgrajene v ali namenjene le uporabi z vtiči in vtičnicami ali s spojkami naprave za gospodinjsko in podobno splošno rabo in če so namenjeni uporabi pri frekvencah, ki niso 50 Hz ali 60 Hz. Ta standard se ne uporablja za: – odklopnike RCBO, namenjene zaščiti motorjev; – odklopnike RCBO, katerih trenutno nastavitev je mogoče prilagoditi s sredstvi, ki so uporabniku na voljo med običajnim delovanjem. Zahteve tega standarda se uporabljajo za običajne okoljske pogoje. Dodatne zahteve so lahko potrebne za odklopnike RCBO, ki se uporabljajo na lokacijah z neugodnimi okoljskimi pogoji. Ta standard ne zajema odklopnikov RCBO z akumulatorji. V Dodatku F so zajeta navodila za usklajevanje odklopnikov RCBO z varovalkami.

1 Scope and object
This International Standard applies to residual current operated circuit-breakers with integral
overcurrent protection functionally independent of, or functionally dependent on, line voltage
for household and similar uses (hereafter referred to as RCBOs), for rated voltages not
exceeding 440 V a.c., rated currents not exceeding 125 A for fixed installation and rated
short-circuit capacities not exceeding 25 000 A for operation at 50 Hz or 60 Hz.
These devices are intended to protect people 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 may 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 also used as a
means for additional protection in the case of failure of the protective means against electric
shock.
This standard applies to devices performing simultaneously the function 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.
These devices are intended for use in an environment with pollution degree 2.
NOTE 1 For environment with higher pollution degree, enclosures giving the appropriate degree of protection should
be used.
*)
In view of some inconsistencies between the English and French versions of IEC 61009-1:1996, it is advisable to use the consolidated
IEC text published in February 2003 for compiling the text of this European Standard.

EN 61009-1:2004 – 4 –
Clause Common modifications
RCBOs within the scope of the present standard are suitable for isolation.
Devices to this standard, are suitable for use in IT systems provided that the requirements of
HD 384.4.473 are complied with.
NOTE 2 The content of the present standard related to the operation under residual current conditions is based on
EN 61008. The content of the present standard related to protection against overcurrents is based on EN 60898.
NOTE 3 RCBOs are essentially intended to be operated by uninstructed persons and designed not to require
maintenance. They may be submitted for certification purposes.
NOTE 4 Installation and application rules of RCBOs are given in HD 384.
NOTE 5 Recommendations for the dimensional coordination between enclosures and RCBOs for mounting on rail
according to EN 60715 or equivalent means are given in CENELEC Report R023-001.
RCBOs 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.
RCBOs of the S type are considered to be sufficiently proof against unwanted tripping even if
the surge voltage causes a flashover and a follow-on current occurs.
NOTE 6 For more severe overvoltage conditions, RCBOs complying with other standards (e.g. EN 60947-2) should
be used.
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 HD 384.4.443).
NOTE 7 For RCBOs having a degree of protection higher than IP20 special constructions may be required.
This standard also applies to RCBOs obtained by the assembly of an adaptable residual
current device with a circuit-breaker. The mechanical assembly shall be effected in the factory
by the manufacturer, or on site, in which case the requirements of Annex G shall apply.
Supplementary requirements may be necessary for RCBOs of the plug-in type.
Particular requirements are necessary for RCBOs integrated in one unit with a socket-outlet or
designed exclusively for being associated locally with a socket-outlet in the same mounting
box.
NOTE 8 Until a specific EN for SRCDs is prepared and approved, for RCBOs integrated in one unit with a socket-
outlet or designed exclusively for being associated locally with a socket-outlet in the same mounting box the
requirements of this standard in conjunction with those of IEC 60884-1 may be used as far as applicable.
This standard does not apply to:
– RCBOs intended to protect motors,
– RCBOs the current setting of which is adjustable by means accessible to the user in
normal service,
– RCBOs having more than one rated current.
The requirements of this standard apply for normal environmental conditions (see 7.1).
Additional requirements may be necessary for RCBOs used in locations having severe
environmental conditions.
RCBOs including batteries are not covered by this standard.
A guide for the co-ordination under short-circuit conditions between a RCBO and another
short-circuit protective device (SCPDs) is given in Annex F.
