_____________
8.1.3 Clearances and creepage distances (see also Annex B)
Replace the third paragraph of this subclause, and the modifications brought to it by
Amendment 1, as follows:
The clearances of items 2 and 4 (except accessible surface after installation, see Note 1) may
be reduced provided that the measured clearances are not shorter than the minimum allowed
in IEC 60664-1 for homogenous field conditions.
Add the following new note after the third paragraph and renumber the existing notes of this
subclause, introduced by Amendment 1, accordingly:
NOTE 1 Accessible surface after installation means any surface accessible by the user when the RCD is installed
according to the manufacturer's instructions. The test finger can be applied to determine whether a surface is
accessible or not.
8.5 Operating characteristics

8.15 Behaviour of RCBOs in case of earth fault currents comprising a d.c. component
Replace the second paragraph as follows:
Compliance is checked by the tests of 9.9.3.

9.7.2 Insulation resistance of the main circuit
Replace the existing text in item c) with the following text:
c) with the RCBO in the closed position, between all poles connected together and the frame
including a metal foil or part in contact with the outer surface of the housing of insulating
material but with the terminal areas kept completely free to avoid flashover between
terminals and the metal foil;
Replace 9.9.1 and the modifications brought to it by Amendment 1 by the following:
9.9.1 Verification of the operating characteristics under residual current conditions
9.9.1.1 Test circuit and test procedure
The RCBO is installed as for normal use.
The test circuit shall be of negligible inductance. For tests according to 9.9.1.2, the test circuit
shall correspond to Figure 4. For tests according to 9.9.1.3, the test circuit shall correspond to
Figure 5 or Figure 6, as applicable.
The instruments for the measurement of the residual current shall display (or allow to
determine) the true r.m.s. value.
NOTE The information for instrument measurement is available at the following CTL webserver:
Unless otherwise specified, the tests are performed with no load at the reference temperature
of 20 °C ± 5 °C.
The RCBO shall perform the tests of 9.9.1.2, 9.9.1.3 and 9.9.1.4, as applicable. Each test is
made on one pole only, taken at random, with five measurements, unless otherwise specified.
For RCBOs having more than one rated frequency, the tests shall be carried out at the lowest
and highest frequency, except for test in 9.9.1.2 e), where verification is performed at only
one frequency.
For RCBOs having multiple settings of residual operating current, the tests shall be made for
each setting.
9.9.1.2 Tests for all RCBOs
The test conditions according to 9.9.1.1 apply to all RCBOs.
a) Verification of correct operation in case of a steady increase of the residual current.

All five measured values shall be situated between I and I .

conditions as closely as possible. The break time is measured five times. No measurement
shall exceed the limiting value specified for I in Table 2, according to the type of RCBO.

c) Verification of correct operation in case of sudden appearance of residual current
– 4 – 61009-1 Amend. 2 © IEC:2013
1) All types
The test circuit being successively calibrated at each of the values of residual current
specified in Table 2, the test switch S and the RCBO being in the closed position, the
test voltage is suddenly established by closing the test switch S .
The RCBO shall trip during each test.
Five measurements of the break time are made at each value of residual current.
No value shall exceed the relevant specified limiting value given in Table 2.
2) Additional test for type S
The test circuit being successively calibrated at each of the values of residual current
specified in Table 2, the test switch S and the RCBO being in the closed position, the
residual current is suddenly established by closing the test switch S for periods
corresponding to the relevant minimum non-actuating times, with a tolerance of %.
− 5
Each application of residual current shall be separated from the previous one by an
interval of at least 1 min.
The RCBO shall not trip during any of the tests.
d) Verification of correct operation in case of sudden appearance of residual currents
between 5 I and 500 A
∆n
The test circuit is calibrated at any two values of the residual current chosen at random
within the range 5 A to 200 A, among the following list 5 A, 10 A, 20 A, 50 A, 100 A,
200 A.
NOTE In Australia the measurement of the break time is made at 5 A, 10 A, 20 A, 50 A, 100 A, 200 A.
The test switch S and the RCBO being in the closed position, the residual current is
suddenly established by closing the test switch S .
The RCBO shall trip during each test. The break time shall not exceed the times given in
Table 2.
The test is made once for each value of residual current on one pole only, taken at
random.
e) Verification of correct operation with load
The tests of 9.9.1.2 b) and 9.9.1.2 c) are repeated, the pole under test and one other pole
of the RCCB being loaded with rated current, this current being established shortly before
the test.
For the test of 9.9.1.2 c), the switch S and the RCBO are in closed position. The residual
current is established by closing S .
f) Tests at the temperature limits
The RCBO shall perform the tests specified in 9.9.1.2 c) under the following conditions,
successively:
1) ambient temperature: –5 °C, off-load;
2) ambient temperature: +40 °C, the RCBO having been previously loaded with the rated
current, at any convenient voltage, until it attains thermal steady-state conditions.
In practice these conditions are reached when the variation of temperature-rise does
not exceed 1 K per hour.
For the tripping tests in 2), the flow of rated current may be interrupted, provided that
the total interruption period does not exceed 30 s. As soon as the sum of interruption
periods exceed 30 s, the RCBO shall be loaded again with rated current for 5 min
before next tripping time measurement.
NOTE Preheating may be carried out at any convenient voltage at either 50 Hz or 60 Hz but auxiliary circuits shall
be connected to their normal operating voltage (particularly for components depending on line voltage).

9.9.1.3 Verification of correct operation at residual currents with d.c. components
This subclause applies to type A RCBOs, under test conditions of 9.9.1.1.
a) Verification of correct operation in case of a continuous rise of residual pulsating direct
current
The test shall be performed according to Figure 5.
The auxiliary switches S and S and the RCBO shall be closed. The relevant thyristor

obtained. Each pole of the RCBO shall be tested twice at
