Replace the existing subclause title and text by the following new subclause:
4.10
4.10 According to the methods of connection
4.10.1 According to the fixation system:
– RCBO’s, the electrical connections of which are not associated with the
mechanical mounting;
– RCBO’s, the electrical connections of which are associated with the mechanical
mounting.
NOTE  Examples of this type are:
– plug-in type;
– bolt-on type;
– screw-in type.
Some RCBO’s 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.
4.10.2 According to the type of terminals:
– RCBO’s with screw-type terminals for external copper conductors;
– RCBO’s with screwless type terminals for external copper conductors;
NOTE 1  The requirements for RCBO’s equipped with this type of terminals are given in Annex ZE.
– RCBO’s with flat quick-connect terminals for external copper conductors;
NOTE 2  The requirements for RCBO’s equipped with this type of terminals are given in Annex ZF.
5 Characteristics of RCBOs

5.3.8 Add, in the seventh column heading of Table 2, a reference to footnote e) after
"500 A".
Delete, in footnote b) of Table 2, "500 A".
Add the following new footnote e):
e)
The verification of the break times at 500 A is only made for the test of 9.9.1.2.c, but in any case
the test is not done for values exceeding the lower limit of the overcurrent instantaneous tripping
range.
6 Marking and other product information
6.Z1 Replace the whole subclause by:
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)).

– 5 – EN 61009-1:2004/A11:2008
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
symbols 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.Z2 Replace the whole subclause by:
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 be repeated.
