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superseded by the preferred symbol IEC 60417-5019 a), given above.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

NOTE 1 No drain hole in the enclosure shall be opened for this test.
NOTE 2 RCBOs tested in enclosures IP55 may also be used in enclosures of a degree of
