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

Odklopniki na preostali (residualni) tok brez vgrajene nadtokovne zaščite za gospodinjsko in podobno rabo (RCCB's) – 1. del: Splošna pravila (IEC 61008-1:1996 + A1:2002, spremenjen)
Ta mednarodni standard se uporablja za odklopnike na preostali (residualni) tok, ki so funkcionalno neodvisni ali odvisni od linijske napetosti, za gospodinjsko in podobno rabo, brez vgrajene nadtokovne zaščite (v nadaljnjem besedilu: RCCB), za nazivne napetosti do vključno 440 V izmenične napetosti, pri čemer nazivna frekvenca dosega 50 Hz, 60 Hz ali 50/60 Hz in nazivni tok ne presega 125 A in ki so namenjeni predvsem zaščiti pred električnim udarom. Te naprave so namenjene zaščiti oseb pred posrednim stikom, pri čemer so izpostavljeni prevodni deli inštalacije povezani z ustreznim ozemljilom. Uporabljajo se lahko za zaščito pred požarom zaradi stalnega ozemljitvenega okvarnega toka brez naprave za nadtokovno zaščito. Tudi odklopniki na preostali (residualni) tok (RCCB) z nazivnim preostalim obratovalnim 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 obratovalno vrednostjo in odprtja zaščitenega tokokroga, kadar preostali tok preseže to vrednost. Odklopniki RCCB so namenjeni uporabi v okolju s stopnjo onesnaženja 2. Primerni so za izolacijo. Odklopniki RCCB, 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). Odklopniki RCCB 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. Odporniki RCCB tipa S naj bi v zadostni meri ščitili pred neželenim odklopom, celo kadar previsoka napetost povzroči preboj in nastane nadaljnji tok. Posebne zahteve so potrebne za: – odklopnike na preostali (residualni) tok z vgrajeno nadtokovno zaščito (glejte standard IEC 61009-1); – odklopnike RCCB, vgrajene v vtiče ali namenjene le uporabi z vtiči in vtičnicami ali s spojkami naprav za gospodinjsko ali podobno splošno rabo; – odpornike RCCB, namenjene uporabi pri frekvencah, ki niso 50 Hz ali 60 Hz. Zahteve tega standarda se uporabljajo za običajne okoljske pogoje (glejte točko 7.1). Dodatne zahteve so lahko potrebne za odklopnike RCCB, ki se uporabljajo na lokacijah z neugodnimi okoljskimi pogoji. Ta standard ne zajema odklopnikov RCCB z akumulatorji.

8.1.2 Replace the second paragraph by:
The switched neutral pole (see 3.3.15) of four-pole RCCBs shall not close after and shall not
open before the other poles.
Compliance is checked by inspection and by manual test, using any appropriate means (e.g.
indicator lights, oscilloscope, etc.).
Add after the sixth paragraph:
RCCBs shall provide in the open position (see 3.3.13) an isolation distance in accordance with
the requirements necessary to satisfy the isolating function (see 8.3).
Indication of the open and closed position of the main contacts shall be provided by one or
both of the following means:
– the position of the actuator (this being preferred); or
– a separate mechanical indicator.
If a separate mechanical indicator is used to indicate the position of the main contacts, this
shall show the colour red for the closed position (ON) and the colour green for the open
position (OFF).
The means of indication of the contact position shall be reliable.
RCCBs shall be designed so that the actuator, front plate or cover can only be correctly fitted
in a manner which ensures correct contact position indication (see Clause 6).
Compliance is checked by inspection and by the tests of 9.9 and 9.11.2.
When means are provided or specified by the manufacturer to lock the operating means in the
open position, locking in that position shall only be possible when the main contacts are in the
open position.
NOTE Locking of the operating means in the ON position is permitted for particular applications.
Compliance is checked by inspection, taking into account the instructions of the manufacturer.

8.1.3 Clearances and creepage distances
The minimum required clearances and creepage distances are given in Table 3 which is
based on the RCCB being designed for operating in an environment with pollution degree 2.
However, the clearances of item 2, 4 and 5 may be reduced provided that the tests at rated
impulse voltage are withstood.
The insulating materials are classified into Material Groups on the basis of their comparative
tracking index (CTI) according to 2.7.1.1 and 2.7.1.3 of IEC 60664-1 and measured according
to IEC 60112.

8.1.Z1 Non-interchangeability
For RCCBs intended to be mounted on bases forming a unit therewith (plug-in type or screw-
