Notes on integration in the load feeders
The SIRIUS solid-state switching devices are very easy to inte-
grate into the load feeders thanks to their industrial connection
method and design.
Particular attention must however be paid to the circumstances
of the installation and ambient conditions, as the performance of
the solid-state switching devices is largely dependent on these.
Depending on the version, certain restrictions must be ob-
served. Detailed information, for example in relation to solid-
state contactors about the minimum spacing and to solid-state
relays about the choice of heat sink, is given in the technical
specifications (see manual) and the product data sheets.
For applications with a very large power requirement it is possi-
ble to use SIVOLT AC power controller. More information on the
product range can be found in the Catalog DA 68 or in the
Industry Mall.

Short-circuit and overload protection
Despite the rugged power semiconductors that are used, solid-
state switching devices respond more sensitively to short cir-
cuits in the load feeder. Consequently, special precautions have
to be taken against destruction, depending on the type of
design.
Siemens generally recommends using SITOR semiconductor
protection fuses. These fuses also provide protection against
destruction in the event of a short circuit even when the solid-
state contactors and solid-state relays are fully utilized.
Alternatively, if there is lower loading, protection can also be pro-
vided by standard fuses or miniature circuit breakers. This pro-
tection is achieved by overdimensioning the solid-state switch-
ing devices accordingly. The technical specifications and the
product data sheets contain details both about the solid-state
fuse protection itself and about use of the devices with conven-
tional protection equipment.
Electromagnetic compatibility (EMC)
The solid-state switching devices are suitable for interference-
free operation in industrial networks without further measures. If
they are used in public networks, it may be necessary for con-
ducted interference to be reduced by means of filters.
This does not include the solid-state contactors for resistive
loads of the special type 3RF23 ..-.CA.. "Low Noise". These com-
ply with the class B limit values up to a rated current of 16 A. If
other versions are used, and at currents of over 16 A, standard
filters can be used in order to comply with the limit values. The
decisive factors when it comes to selecting the filters are essen-
tially the current loading and the other parameters (operational
voltage, design type, etc.) in the load feeder.
Suitable filters can be ordered from EPCOS AG. You can find
