_____________
1 Scope
Delete Note 8 and replace it by the following paragraph and new Note 8:
For RCBOs incorporated in, or intended only for association with socket-outlets, the
requirements of this standard 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 standard.
2 Normative references

Amendment 2:2005
4.10 According to the method of connection
In the subclause, replace the existing text and note by the following:
– RCBOs, the electrical connections which are not associated with the mechanical
mounting;
– RCBOs, the electrical connections which are associated with the mechanical mounting.
NOTE Examples of this type are:
– plug-in type;
– bolt-on type;
– screw-in type.
Some RCBOs may be of the plug-in type or bolt-on type on the line side only, the load terminals being usually
suitable for wiring connection.
Add the following new subclause:
According to the type of terminals
4.13
– RCBOs with screw-type terminals for external copper conductors;
– RCBOs with screwless type terminals for external copper conductors;
NOTE 1 The requirements for RCBOs equipped with these types of terminals are given in Annex J.
– RCBOs with flat quick-connect terminals for external copper conductors;
NOTE 2 The requirements for RCBOs equipped with these types of terminals are given in Annex K.
– RCBOs with screw-type terminals for external aluminium conductors.
NOTE 3 The requirements for RCBOs equipped with this type of terminal are given in annex L.
Table 2 – Limit values of break time and non-actuating time for alternating residual
currents (r.m.s. values) for type AC and A RCBO
In the table, replace the word “non-operating” by “non-actuating".
c)
In the table, at the end of Footnote , add the following text:
For the tests of 9.9.1.3 and 9.9.1.4 b), the current I is established so that the vector sum IΔt + I is equal to the
Δt n
lower limit of the overcurrent instantaneous tripping range, according to type B, C or D, as applicable.
6 Marking and other product information
Replace the contents of item l) by the following:
l) the position of use, if necessary;

– 4 – 61009-1 Amend.1 © IEC:2012
Replace the third paragraph after Note 1 by the following:
If, for small devices, the space available does not allow all the above data to be marked, at
least the information under d), f), n), p) and r) (only for type A) shall be marked and visible
when the device is installed. The information under a), b), c), h) , l), r) (only for type AC) and
s) may be marked on the side or on the back of the device and be visible only before the
device is installed. The information under q) may be on the inside of any cover which has to
be removed in order to connect the supply wires. Any remaining information not marked shall
be given in the manufacturer's catalogues.
Replace in the eleventh paragraph after Note 1, the word “circuit” by “conductor”.
Add the following text at the end of Clause 6:
For universal terminals (for rigid-solid, rigid-stranded and flexible conductors):
– no marking.
For non-universal terminals:
– terminals declared for rigid-solid conductors only shall be marked by the letters “s” or
"sol";
– terminals declared for rigid (solid and stranded) conductors only shall be marked by the
letter "r".
The markings should appear on the RCBO or, if the space available is not sufficient, on the
smallest package unit or in technical information.
8.1.3 Clearances and creepage distances (see Annex B)
Replace the existing text in this subclause by the following:
The minimum required clearances and creepage distances are given in Table 7 which is
based on the RCBO being designed for operating in an environment with pollution degree 2.
Compliance for item 1 in Table 7 is checked by measurement and by the test of 9.7.7.4.1 and
9.7.7.4.2. The test is carried out with samples not submitted to the humidity treatment
described in 9.7.1.
The clearances of items 2 and 4 may be reduced provided that the measured clearances are
not shorter than the minimum allowed in IEC 60664-1 for homogenous field conditions.
In this case, after the humidity treatment described in 9.7.1, compliance for item 2 and 4 and
arrangements of 9.7.2 items b), c), d) and e) is checked in the following order:
– Tests according to 9.7.2 to 9.7.6 as applicable;
– Test according to 9.7.7.2 is applied with test voltages given in Table 19 with test
arrangements of 9.7.2 items b), c), d), e).
If measurement does not show any reduced clearance, test 9.7.7.2 is not applied.
Compliance for item 3 in Table 7 is checked by measurement.
NOTE 1 All measurements required in 8.1.3 are carried out in Test sequence A on one sample and the tests
9.7.7.2 are carried out before 9.7.1 on three samples of Test sequence B.
Parts of PCBs connected to the live parts protected against pollution by the use of a type 2
protection according to IEC 60664-3 are exempt from this verification.

61009-1 Amend.1 © IEC:2012 – 5 –
The insulating materials are classified into material groups on the basis of their comparative
tracking index (CTI) according to 4.8.1 of IEC 60664-1:2007.
NOTE 2 Information on the requirements for design of solid insulation and appropriate testing is provided in
IEC 60664-1:2007, 5.3 and 6.1.3.
NOTE 3 For clearances on printed wiring material, the following Note 3 in Table F.2 in 60664-1:2007 can be used:
“For printed wiring material, the values for pollution degree 1 apply except that the value should not be less than
0,04 mm, as specified in Table F.4.” For creepage distances on printed wiring material, distances in Table F.4 in
60664-1:2007 can be used if protected with a coating meeting IEC 60664-3 requirements and tests.
NOTE 4 The dimensioning of clearances and creepage distances for spacings equal to or less than 2 mm for
printed wiring board may be optimised under certain conditions in case of use of IEC 60664-5. Only humidity levels
HL 2 and HL3 are considered.
Table 7 – Minimum clearances and creepage distances
Delete, in this table, point 5 in the first column and the existing Note 3.
e
Replace, in the table, the last sentence of the existing Footnote by the following text:
When interpolating, linear interpolation shall be used and values shall be rounded to the same number of digits as
the values picked up from the tables. For determination of creepage distances, see Annex B.
8.1.4.4
In the subclause, replace the existing text by the following:
Current-carrying parts including parts intended for protective conductors, if any, shall be
made of a metal having, under the conditions occurring in the equipment, mechani
