6.Z1 Standard marking
Each RCCB shall be marked in a durable manner according to the following Table Z3.
If a degree of protection higher than IP20 according to EN 60529 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 manufacturer shall state the Joule integral I2t and the peak current Ip withstand
capabilities of the RCCB. Where these are not stated, minimum values as given in
Table 15 apply.
The manufacturer shall give the reference of one or more suitable SCPDs in his
catalogues and in a sheet accompanying each RCCB.
For RCCBs classified according to 4.1.2.1 and opening with delay in case of failure of
the line voltage the manufacturer shall state the range of such delay.
For RCCBs other than those operated by means of push-buttons the open position
shall be indicated by the symbol "O" and the closed position by the symbol "I" (a short
straight line). Additional national symbols for this indication are allowed. Provisionally
the use of national indications only is allowed. These indications shall be readily

Clause Common modification
visible when the RCCB is installed.
For RCCBs 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 RCCB. If a push-button is used
for closing the contact 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.
The suitability for isolation, which is provided by all RCCBs 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. 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 RCCBs shall be marked with the following:
- rated current or maximum rated current;
- trade mark.
The 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 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 RCCB 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

+40 °C, are admissible during storage and transportation. These conditions
should be taken into account in the design of the device.

Add footnote 8) as follows:
8) For installations at higher altitudes, it is necessary to take into account the
reduction of the dielectric strength and of the cooling effect of the air. RCCBs
intended to be so used shall be designed specially or used according to an
agreement between manufacturer and user. Information given in the
manufacturer's catalogue may take the place of such an agreement.

RCCBs for use at temperatures between -25 °C and +40 °C

Enclosed-type RCCBs are tested in their enclosure, unenclosed-type RCCBs are
mounted in an individual enclosure with a degree of protection IP55, and are
connected as for normal use (see Figure 4a).
NOTE 1 No drain hole in the enclosure shall be opened for this test.

- 13 - EN 61008-1:2012
Clause Common modification
NOTE 2 RCCBs tested in enclosures IP55 may also be used in enclosures of a degree
of protection other than IP55 within the temperature range of –25 °C to +40 °C.
The RCCB (including the enclosure) is brought into a suitable test chamber with an
ambient air temperature of (23 ± 2) °C and a relative humidity of (93 ± 3) %. The
volume ratio of the test chamber to the test samples (including enclosures) shall be
greater than 50.
The RCCB is in the ON-position without load and shall be subjected to the following
cycle (see Figure Z3).
For the first 6 h (stabilization period) the temperature is kept at (23 ± 2) °C and the
humidity at (93 ± 3) %. Within the next 6 h the ambient air temperature is decreased
to (-25 ± 2) °C without any supply of humidity. This temperature of (-25 ± 2) °C is kept
for 6 h. Within the next 6 h the temperature is increased to (+ 23 ± 2) °C and the
relative humidity is increased to (93 ± 3) % (end of the first cycle). This cycle is
performed five times.
During these cycles the RCCB shall not trip.
During the fifth cycle, at the end of the period at (-25 ± 2) °C, an a.c. residual current
is passed through one pole of the RCCB (see Figure 4a)
and
– for RCCBs of the general type, the residual current is calibrated to 1,25 I

In addition, RCCBs of type A are tested with pulsating d.c. residual currents

corresponding to Figure 4b

deterioration impairing the further use of the RCCB and it shall be possible to switch
on the RCCB, without the presence of any residual current, at the temperature of -25
°C.
