2) Calculation according draft proposal IEC 60939−1 Ed. 3 (2008−10−29), annex A, ”Calculation of leakage current”.
In practice are up to double values to be expected due to the insulation resistance values of the used ceramic capacitors . For the medical
version results computationally the value 0. In practice are values 1 ... 2 µA to be expected due to the insulation resistance values of the used
ceramic capacitors.
3) ENEC approval at 12 A and 15A types maximum with 10 A and at 20 A type maximum with 16 A feasible.

Caution and warnings
Please note the advices in our data book “EMC Filters” (latest edition); attention should
be paid to the chapter “General safety notes”.
It shall be ensured that only qualified persons (electricity specialists) are engaged on work
such as planning, assembly, installation, operation, repair and maintenance. They must
be provided with the corresponding documentation.
Danger of electric shock. EMC filters contain components that store an electric charge.
Dangerous voltages can continue to exist at the filter terminals for longer than five min-
utes even after the power has been switched off.
The protective earth connections shall be the first to be made when the EMC filter is
installed and the last to be disconnected. Depending on the magnitude of the leakage cur-
rents, the particular specifications for making the protective−earth connection must be ob-
served.
Impermissible overloading of the EMC filter, such as with circuits able to cause reso-
nances, impermissible voltages at higher frequencies etc. can lead to bodily injury and
death as well as cause substantial material damages (e.g. destruction of the filter hous-
ing).
EMC filters must be protected in the application against impermissible exceeding of the
rated currents by overcurrent protective.
In case of leakage currents > 3.5 mA you shall mount the PE conductor stationary with
the required cross section before beginning of operation and save it against disconnect-
ing. For leakage currents IL 5) < 10 mA the PE conductor must have a KU value 4) of 4.5;
for leakage currents IL 10 mA the PE conductor must have a KU value of 6.
4) The KU value (symbol KU) is a classification parameter of safety−referred failure types designed to ensure protection against hazardous
body currents and excessive heating.
A value of KU = 4.5 with respect to interruptions is attained:
− with a permanently connected protective earth circuit 1.5 mm2
− with a protective earth circuit 2.5 mm2 connected via shroud connectors (IEC 60309−2).
KU = 6 with respect to interruptions is achieved for fixed−connection lines 10 mm2 where the type of connection and line layout corre-
spond to the requirements for PEN conductors as specified in relevant standards.
5) IL = leakage current let−go

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for cer-
tain areas of application. These statements are based on our knowledge of typical requirements
that are often placed on our products in the areas of application concerned. We nevertheless ex-
pressly point out that such statements cannot be regarded as binding statements about the
suitability of our products for a particular customer application. As a rule, EPCOS is either un-
familiar with individual customer applications or less familiar with them than the customers them-
selves. For these reasons, it is always ultimately incumbent on the customer to check and decide
whether an EPCOS product with the properties described in the product specification is suitable for
use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or failure
before end of their usual service life time cannot be completely ruled out in the current state
of the art, even if they are operated as specified. In customer applications requiring a very high
level of operational safety and especially in customer applications in which the malfunction or failure
of an electronic component could endanger human life or health (e.g. in accident prevention or life−
saving systems), it must therefore be ensured by means of suitable design of the customer applica-
tion or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that
no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic
component.
3. The warnings, cautions and product−specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this publica-
tion may contain substances subject to restrictions in certain jurisdictions (e.g. because they
are classed as hazardous). Useful information on this will be found in our Material Data Sheets on
the Internet (www.epcos.com/material). Should you have any more detailed questions, please con-
tact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this publi-
cation may change from time to time. The same is true of the corresponding product specifica-
tions. Please check therefore to what extent product descriptions and specifications contained in
this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently,
we cannot guarantee that all products named in this publication will always be available. The afore-
mentioned does not apply in the case of individual agreements deviating from the foregoing for cus-
tomer−specific products.
6. Unless otherwise agreed in individual contracts, all orders subject to the current version of the
“General Terms of Delivery for Products and Services in the Electrical Industry” published
by the the German Electrical and Electronics Industry Association (ZVEI).
