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. 4
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. Your Highlights benefits at a glance Fits into all common medium-voltage switchgear 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 You can rely on our comprehensive technical support for fast and competent solutions to your problems. CAD documentation and training take the load off your day-to-day business. Deployed in power supply or in industrial enterprises, our SION portfolio offers safe, efficient, and flexible modules for all medium-voltage switchgear
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. Vacuum interrupters do not contain a medium that can be ionized, so the switching 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. 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 6
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. Your benefits at a glance More than 40 years of knowhow in vacuum switching technology Constant dielectric, constant contact resistance High level of reliability in all switching applications Maintenance-free vacuum circuit-breakers up to 10,000 operating cycles (optionally up to 30,000 operation cycles) Safe in all conditions Our high SION quality is regularly proven in independent tests 7
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. 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. The compact and light SION fits into all medium-voltage switchgear 8
