“
Annex ZN
(normative)
Additional requirements and tests for RCBOs consisting of one residual current protection
function and several independent two-pole overcurrent protection functions
Introduction
If not otherwise mentioned, Annex ZN amends specific requirements of this document. All requirements not
mentioned in this annex shall be applied unchanged.
In Clause ZN.x below, the same numbering of the subclauses has been kept as in the main document.
ZN.1 Scope
This annex applies to RCBOs with one residual current protection function and several independent two-
pole overcurrent protection functions.
NOTE These devices are intended for the protection of independent single phase final circuits.
ZN.3 Definitions
The following definition applies additionally:
ZN.3.3.24 Residual current protection function
Function performing simultaneously the functions of detection of the residual current, of comparison of the
value of this current with the residual operating value, and containing the means to activate the tripping
mechanism of all incorporated overcurrent functions.
ZN.4 Classification
Replace 4.3 with the following:
ZN.4.3 According to the number of poles and outputs
— RCBO with 2-pole input, and a maximum of 3 identical two-pole outputs (each with one overcurrent
protected pole);
— RCBO with 4-pole input and a maximum of 3 identical two-pole outputs (each with one overcurrent
protected pole).
NOTE RCBOs with non-identical overcurrent protected poles (e.g. different rated currents or different
instantaneous tripping ranges B, C or D) and with two protected poles are under consideration.
Replace 5.3.1 with:
ZN.5.3.1 Rated operational voltage (Ue)
Standard rated operational voltages are:
Rated operational voltages for use in systems
RCBO
230 V, 230 V/400 V, 400 V
Input 230 V
2-poles
Output 230 V
Input 400 V
4-poles
Output 230V
Replace 5.3.2 with:
ZN.5.3.2 Rated current (I )
n
Preferred rated currents are:
Rated current (I )
RCBO
n
Input Sum of all output currents
2-poles
Output 6 A – 10 A – 13 A – 16 A – 20 A
Input
4-poles 6 A – 10 A – 13 A – 16 A – 20 A
Output
When reference is made to rated current I in the main standard or in this annex, it corresponds to the output
n
rated current.
The maximum rated output current is 20 A.
ZN.6.3 Requirements for marking
Table Z3 — Requirements for marking
Replace c) with:
c) Rated operational voltage of input and output with the symbol ∼
Replace d) with:
At the input: Rated current with the symbol “A”
At the output: Rated current without symbol “A” preceded by the symbol of overcurrent instantaneous
tripping (B, C or D), for example B 16;
ZN.8.1.2 Mechanism
The requirements of 8.1.2 apply, with following changes:
The first paragraph is modified as follows:
The moving contacts of both poles of each independent overcurrent protection function shall be
mechanically coupled so that both poles, except the switched neutral, if any, make and break substantially
together, whether operated manually or automatically.
Add the following:
The RCD function shall trip all overcurrent protection functions in case of a residual current. Each two-pole
output shall trip individually under an overcurrent condition without causing operation of the other two-pole
outputs.
Compliance is checked by inspection and by the tests of 9.9.1 and 9.9.2.
ZN.9.8 Test of temperature-rise
ZN.9.8.2 Test procedure
Requirements from 9.8.2 apply with the following changes:
A current equal to I of the overcurrent output is passed simultaneously through all overcurrent outputs,
n
ensuring that the RCD function is loaded to the input I for a period of time sufficient for the temperature-
n
rise to reach the steady-state value. In practice, this condition is reached when the variation of the
temperature-rise does not exceed 1 K per hour.
Replace 9.9.2.1 with:
ZN.9.9.2.1 Test of time-(over)current characteristic
a) A current equal to I is passed for the conventional time (see 8.5.2.1 and 8.5.2.2 a)) through all outputs,
n
starting from cold (see Table 10). The RCBO shall not trip. The current is then steadily increased within
5 s to 1,45 I in one output (conventional tripping current). The overcurrent protection function shall trip
n
within one hour.
b) A current equal to 1,13 I (conventional non-tripping current) is passed for the conventional time (see
n
8.5.2.1 and 8.5.2.2 a)) through one randomly chosen output, starting from cold (see Table 10). The
RCBO shall not trip.
The current is then steadily increased within 5 s to 1,45 I (conventional tripping current). The
n
corresponding overcurrent protection function shall trip within one hour.
A different output shall be used for each of the samples.
c) A current equal to 2,55 I is passed through one randomly chosen output, starting from cold. The
n
opening time of the corresponding overcurrent protection function shall be not less than 1 s nor more
than 60 s.
A different output shall be used for each of the samples.
ZN.9.9.2.2 Test of instantaneous tripping and correct opening of the contacts
Replace a), b), c) and d) with:
a) General test conditions
For the lower values of the test current of 9.9.2.2 b), 9.9.2.2 c) and 9.9.2.2 d) respectively
the test is made once, at any convenient voltage.
For the upper value of the test current, the test is carried out at rated operational voltage U (phase to
e
neutral) with a power factor between 0,95 and 1 on each output, the following sequence of operation is
performed:
O-t-CO-t-CO-t-CO
the interval t being as defined in 9.12.11.1. The tripping time of the O operation is measured. After each
operation the indicating means shall show the open position of the contacts.
b) For B type RCBOs
A current equal to 3 I is passed individually through each output, starting from cold.
n
The opening time shall be not less than 0,1 s.
A current equal to 5 I is then passed individually through each output, again starting from cold.
n
The corresponding overcurrent protection function shall trip in a time less than 0,1 s.
c) For C type RCBOs
A current equal to 5 I is passed individually through each output, starting from cold.
n
The opening time shall be not less than 0,1 s.
A current equal to 10 I is then passed individually through each output, again starting from cold.
n
The corresponding overcurrent protection function shall trip in a time less than 0,1 s
d) For D type RCBOs
A current equal to 10 I is passed individually through each output, starting from cold. The opening time
n
shall be not less than 0,1 s.
A current equal to 20 I or to the maximum instantaneous tripping current (see Clause 6, item t) is then
n
passed individually through each output, again starting from cold.
The corresponding overcurrent protection function shall trip in a time less than 0,1 s.
Replace 9.9.2.3 with:
ZN.9.9.2.3 Test of effect of ambient temperature on the tripping characteristic
a) The RCBO is placed in an ambient temperature of (35 ± 2) K below the ambient air reference
temperature until it has attained steady-state temperature. A current equal to 1,13 I (conventional non-
n
tripping current) is passed simultaneously t
