Residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBOs) - Part 1: General rules (IEC 61009-1:2010, modified)

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.

Interrupteurs automatiques à courant différentiel résiduel avec dispositif de protection contre les surintensités incorporé pour usages domestiques et analogues (DD) - Partie 1: Règles générales( CEI 61009-1:2010, modifiée)

La CEI 61009-1:2010 s'applique aux interrupteurs automatiques avec protection contre les surintensités incorporé, à courant différentiel résiduel, fonctionnellement indépendants ou fonctionnellement dépendants de la tension d'alimentation, pour installations domestiques et analogues (en abrégé 'DD' dans la suite du texte), ayant une tension assignée ne dépassant pas 440 V alternatifs, avec des fréquences assignées de 50 Hz, 60 Hz ou 50/60 Hz et un courant assigné ne dépassant pas 125 A et un pouvoir de coupure ne dépassant pas 25 000 A pour fonctionnement à 50 Hz ou 60 Hz. Cette troisième édition annule et remplace la deuxième édition, publiée en 1996, ainsi que l'amendement 1 (2002) et l'amendement 2 (2006), dont elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- révision complète des séquences CEM, incluant le nouvel essai T.2.6, déjà approuvé dans la CEI 61543;
- clarification des caractéristiques courant/temps des DDR incluses dans les Tableaux 2 et 3;
- révision de la procédure d'essai pour IΔn< /sub> entre 5 A et 200 A;
- essais pour l'emploi des DD dans les systèmes IT;
- procédure d'essai concernant le courant continu 6 mA superposé au courant de défaut;
- des améliorations mettant en relief les DDR avec sensibilité multiple;
- des alignements avec la CEI 60898-1.

Odklopniki na preostali (residualni) tok z vgrajeno nadtokovno zaščito za gospodinjsko in podobno rabo (RCBO's) - 1. del: Splošna pravila (IEC 61009-1:2010, spremenjen)

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.

6.Z1 Standard marking

Each RCBO shall be marked in a durable manner according to the following Table Z3.

For RCBOs other than those operated by means of push-button, the open position shall

be indicated by the symbol "Ο" and the closed position by the symbol "|" (a short straight

line).

Additional national symbols are allowed for this indication. Provisionally the use of national

indications only is allowed. These indications shall be readily visible when the RCBO is

installed.

For RCBOs operated by means of two push-buttons, the push-button designed for the opening

operation only shall be RED and/or be marked with the symbol "O".
RED shall not be used for any other push-button of the RCBO.

If a push-button is used for closing the contacts and is evidently identified as such, its depressed

position is sufficient to indicate the closed position.

If a single push-button is used for closing and opening the contacts and is identified as such, the

button remaining in its depressed position is sufficient to indicate the closed position. On the

other hand, if the button does not remain depressed, an additional means indicating the position

of the contacts shall be provided.

If it is necessary to distinguish between the supply and the load terminals, they shall be clearly

marked (e.g. by "line" and "load" placed near the corresponding terminals or by arrows indicating

the direction of power flow).

Terminals exclusively intended for the connection of the neutral circuit shall be indicated by the

letter N.

Terminals intended for the protective conductor, if any, shall be indicated by the symbol

(IEC 60417-5019 a)).

NOTE The symbol (IEC 60417-5017 a)), previously recommended, shall be progressively

superseded by the preferred symbol IEC 60417-5019 a), given above.

If a degree of protection higher than IP20 is marked on the device, it shall comply with it,

whichever the method of installation. If the higher degree of protection is obtained only by a

specific method of installation and/or with the use of specific accessories (e.g. terminal covers,

enclosures, etc.), this shall be specified in the manufacturer's literature

The suitability for isolation, which is provided by all RCBOs of this standard, may

be indicated by the symbol on the device. When affixed, this marking may be included in a wiring

diagram, where it may be combined with symbols of other functions, (e.g. overload protection, or

other symbols of IEC TC 3). When the symbol is used on its own (i.e. not in a wiring diagram),

combination with sym bols of other functions is not allowed.
The base for plug-in RCBOs shall be marked with the following:
- rated current or maximum rated current;
- trade mark.

Marking shall be indelible, easily legible and not be placed on screws, washers or other

removable parts.
Compliance is checked by inspection and by the test of 9.3.
6.Z.2 Add the following subclause
6.Z2 Additional marking

Additional marking to other standards (EN or IEC or other) or additional requirements

are allowed under the following conditions:
- the RCBO shall comply with all the requirements of the additional standard;

- the relevant standard to which the additional marking refers shall be indicated

adjacent to this marking and shall be clearly differentiated or separated from the

standard marking according to 6.Z1.
Compliance is checked by inspection and by carrying out all the test sequences

required by the relevant standard. Equivalent or less severe test sequences need not
