Compact design for perfect switching
– everywhere
The worldwide demand for power continues to increase at a rapid rate.
This is placing ever greater performance demands on utilities and industrial
enterprises. Gain a competitive edge and adeptly achieve your switching
tasks in medium-voltage networks: with vacuum circuit-breakers for quick
and simple integration in any switchgear, offering everything that is needed
for a long service life and switching under short-circuit conditions – that is
what our SION 3AE vacuum circuit-breakers have been developed for.

SION – simply reliable
With SION 3AE vacuum circuit-breakers
you have chosen a highly innovative product based on four decades of Siemens
expertise in vacuum switching technology. Perfectly tailored to your needs as a
switchgear builder or user in the energy
industry or an industrial plant, SION
makes for increased productivity and
availability while keeping maintenance
costs to negligible levels.
Innovative design
You can install SION circuit-breakers in all
common air-insulated medium-voltage
switchgear. Even retrofitting into existing switchgear is simple with SION.
Their compact design, in particular, their
shallow depth and narrow width, means
you can reduce the variety of switchgear
panels and concentrate high performance into a compact space -
across a wide range of voltage levels.
Setting new standards in design, functionality, and flexibility, the SION circuitbreaker can be integrated quickly and
simply into any switchgear, and is reliable and easy to operate with its clearly
laid out control board.
Support when you need it
Whether you choose the fixed-mounted
or the withdrawable version, and whatever pole-center distance and width
across flats you require – we will support
and advise you in selecting devices and
installing them into the panels.

Siemens vacuum switching
technology – precision down
to the last detail
The excellent economic and technical
characteristics of vacuum arc quenching
makes the vacuum circuit-breaker the
most frequently deployed switching
device in the world in the voltage range
1 kV to 52 kV.
The core of every
vacuum circuit-breaker
The vacuum interrupter as the arc-quenching medium is the central component
of every vacuum circuit-breaker. As the
pioneer in vacuum switching technology
in Europe, Siemens is your trusted partner with more than 40 years of experience in this field.
ching behavior is determined by the
material the contacts are made of.
We therefore place extremely high
demands on this material
Reliable switching –
throughout a long (circuit-breaker) life
The hermetically sealed vacuum interrupters are independent of external
influences. Vacuum technology has
many advantages: a constant dielectric,
no decomposition products, no oxidation, so consistently metallic contact surfaces and constant contact resistance –
throughout the lifetime of the product.
Vacuum interrupters do not contain a
medium that can be ionized, so the swit-
Highly automated and modern machines
and production processes achieve manufacturing accuracy that go far beyond the
requirements of the quality standards of
ISO 9001 and ISO 14001

Equipped for all switching applications
Reliable and safe under all conditions
SION vacuum circuit-breakers have low
chopping currents, are restrike-free, and
switch normal and short-circuit currents,
which means they can be used for all
switching applications.
SION vacuum circuit-breakers have been
developed into highly modern products
with a small number of moving components in the arcing chamber. Their extreme
reliability is among others also proven by
the very high mean time to failure (MTTF)
values of the vacuum interrupters.
As the core component, the maintenance-free vacuum interrupters make
these modern SION circuit-breakers
maintenance free for up to 10,000 operating cycles (optionally up to 30,000
operation cycles).
Air insulation makes for optimum cooling
during continuous operation, so that the
highest possible nominal currents can be
reached in the switchgear.

SION 3AE vacuum circuit-breaker –
with green benefits
The SION 3AE vacuum circuit-breaker is our most modern
product, which is manufactured using state-of-the-art
machines. For voltage levels of 7.2 kV to 24 kV we offer a
wide range of pole-center distances and widths across
flats as well as different accessory packages. Withdrawable modules, contact arms, contacts, and bushings permit
simple integration in all common medium-voltage
switchgear.
The compact and light SION
fits into all medium-voltage
switchgear

Whether you want to switch overhead lines, cables, transformers, capacitors, or motors, the SION 3AE is easy to
integrate into your panels.
Compact design for a long service life
The more compact and lighter construction offers practical benefits for implementing a clear panel design. Moreover, the compact design combined with a long service life
and freedom from maintenance of the circuit-breakers for
10,000 operating cycles is kind to the environment.
