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 designYou can install SION circuit-breakers in all common air-insulated medium-voltage switchgear. Even retrofitting into existing switchgear is simple with SION. Their com-pact design, in particular, their shallow depth and narrow width, means you can reduce the variety of switchgear panels and concentrate high performance into a com-pact space – across a wide range of voltage levels.

Deployed in power supply or in industrial enterprises, our SION portfolio offers safe, efficient, and flexible modules for all medium-voltage switchgear

Setting new standards in design, func-tionality, and flexibility, the SION circuit-breaker 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 itWhether 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.

You can rely on our comprehensive tech-nical support for fast and competent solutions to your problems. CAD docu-mentation and training take the load off your day-to-day business.

Your benefits at a glance

• Fits into all common medium-voltage switch-gear from 7.2 kV to 24 kV

• Short-circuit breaking currents up to 40 kA

• Nominal currents up to 3,150 A

• Extremely compact design with identical connection dimensions across a wide range of voltage levels

• Compact front for simple operation

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-breakerThe vacuum interrupter as the arc-quench-ing medium is the central component of every vacuum circuit-breaker. As the pio-neer in vacuum switching technology in Europe, Siemens is your trusted partner with more than 40 years of experience in this field.

Vacuum interrupters do not contain a medium that can be ionized, so the switch-ing 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) lifeThe hermetically sealed vacuum interrupt-ers 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 life-time of the product.

Highly automated and modern machines and production

processes achieve manufac-turing accuracy that go far

beyond the requirements of the quality standards of

ISO 9001 and ISO 14001

Siemens vacuum switching technology – precision down to the last detail

Equipped for all switching applicationsSION 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.

As the core component, the maintenance-free vacuum interrupters make these mod-ern SION circuit-breakers maintenance free for up to 10,000 operating cycles (option-ally up to 30,000 operation cycles).

Reliable and safe under all conditions SION vacuum circuit-breakers have been developed into highly modern products with a small number of moving components in the arcing chamber. Their extreme reli-ability is among others also proven by the very high mean time to failure (MTTF) values of the vacuum interrupters.

Air insulation makes for optimum cooling during continuous operation, so that the highest possible nominal currents can be reached in the switchgear.
