General remarks:
The test results presented in this report relate only to the object tested.
This report shall not be reproduced, except in full, without the written approval of the Issuing testing laboratory.
"(See Enclosure #)" refers to additional information appended to the report.
"(See appended table)" refers to a table appended to the report.
Note: This TRF includes EN Group Differences together with National Differences and Special National
Conditions, if any. All Differences are located in the Appendix to the main body of this TRF.
Throughout this report a comma (point) is used as the decimal separator.
This test report has to be read in conjunction with 5007032-1181-0008/147768-01.
General product information:
The suffix “DS” in the marking means that the SPD is provided with remote control contact.

If not otherwise specified all tests have been carried out on three samples per test sequence.
Terminal tests have been carried out on three terminals of each construction used.
Impulse tests have been carried out according to chapters 7.1.1 to 7.1.4.

1,0* Ipeak = _____
If a product covered by another international standard than IEC 61643 incorporates SPD technology the
requirements of the other international standard shall apply to those parts of the product not influenced by the
presence of the SPD technology.
Unless otherwise specified, a.c. values given in this report are r.m.s. values.
If not otherwise specified the tests have been performed in free air and at an ambient temperature
of (20 ± 15)°C.
If not otherwise specified, for all tests where a power supply at UC is required, the voltage
+0
tolerance for testing was /-5%.
If the SPD is supplied with integral cables, the full length of these cables forms part of the SPD under test,
except for the determination of the measured limiting voltage 7.5, where a lead length of 150 mm is
used.
SPD disconnectors have been selected and connected as required by the manufacturer, where applicable.
SPD disconnectors have been tested with the SPD during the sequence of type tests of 7.7 and 7.8.3,
except for RCDs, which are not tested during the operating duty test according to 7.7.1.
For SPDs having more than one mode of protection, for which the manufacturer declares a voltage protection
level, the tests have been performed on each mode, with the values chosen according to the manufacturer's
declaration, using new samples each time. For three phase devices in which the protective component
circuitry per given mode is identical, the testing may be performed on each of the three phases which fulfils
the three sample requirement.
If the manufacturer sets different requirements for the external SPD disconnector(s) depending upon the
prospective short-circuit current of the supply system, all relevant test sequences have been performed for
every combination of required SPD disconnector(s) and corresponding prospective short-circuit currents.

Standby Power Consumption and Residual Current
Test
The SPD is connected to a voltage source at its
maximum continuous operating voltage (UC) according
the manufacturers instruction. The Apparent Power
(Volt-Amperes) consumed by the SPD is measured.
The current at the PE terminal is called the residual
current..
Notes
1:
If the manufacturer allows more than one
configuration for the SPD installation, this test
should be performed for every configuration.
2:
The true r.m.s. current value is measured.

Electromagnetic compatibility
7.10.1
Electromagnetic immunity
SPDs either incorporating no electronic circuits or
incorporating electronic circuits in which all
components are passive (for example diodes,
resistors, capacitors, inductors, varistors and other
surge protective components) are not sensitive to
normal electromagnetic disturbances and therefore
no immunity tests are required.
The requirements for SPDs containing electronic
circuits are under consideration.
7.10.2
P
N/A
Electromagnetic emission
For SPDs not incorporating electronic circuits, or
incorporating electronic circuits that do not generate
fundamental frequencies greater than 9 kHz in
normal operation, electromagnetic disturbances can
only be generated during protective operations.
The duration of these disturbances is in the order of
microseconds to milliseconds.
The frequency, level and the consequences of these
emissions are considered as part of the normal
electromagnetic environment of low-voltage
installations. Therefore, the requirements for
electromagnetic emissions are deemed to be satisfied
and no verification is necessary.
The requirements for SPDs containing electronic
circuits generating fundamental frequencies greater
than 9 kHz are under consideration.

Thermal stability test
Test for SPDs having no switching components in
series with other components - Procedure a)
If the voltage across the SPD falls below Ucs during the
test, the current regulation is discontinued and the
voltage is adjusted back to Uc (EN 61643-11 Ucs)
and maintained for a duration of 15 min. Continuous
current monitoring is no longer required.
Source short-circuit current capability does not limit the
current before any disconnector operates. The
maximum available current value does not exceed the
short circuit withstand capability declared by the
manufacturer.
