Switch disconnectors with Sitor fuses

The 3KF switch disconnectors with Sitor fuses (LV HRC design) are suitable for AC applications up to 690 volts and DC applications up to 440 volts.

Charging of electric vehicles

With VersiCharge, electric vehicles can be charged quickly, safely and cost-effectively. Compared to the previous model, the charging unit has a more compact design. It meets the higher protection class IP 56 and thus can also be installed in outdoor areas.

7KT PAC1600 measuring devices

The new compact 7KT PAC1600 measuring devices are installed using a space-saving design in power and installation distribution boards. They detect base electrical quantities and show the values directly on the display of the relevant measuring device.

Multichannel current measuring system SEM3

The multichannel current measuring system SEM3 is used in the main power distribution and consists of current transformers, measurement modules and a central controller. The scalable complete system can detect up to 45 measurement points in a building.

Arc fault detection device (AFDD) 5SV6

Siemens presents at Light+Building 2018 the world's first arc fault detection device (AFDD) with integrated line protection in one modular width (MW).

New vacuum circuit breakers for higher voltage levels

With the Sion 3AE5, Siemens has enhanced its portfolio of vacuum circuit breakers for medium-voltage power distribution. The new circuit breaker is used as an incoming main in air-insulated medium-voltage equipment. In comparison to the previous model, the Sion 3AE5, at a rated voltage of 17.5 Kilovolt (kV), handles higher rated short-circuit currents up to 31.5 kilo amperes (kA) and can run rated operational currents up to 2500 amperes (A). The new, wider drive cover offers room for an additional release and thus more flexible options for use. The circuit breaker can be expanded with different release and interlock mechanisms. The electrical closing lockout provides for more safety. As a key component of a switchboard, circuit breakers reliably switch all operational currents and residual currents, ensure the load flow in the network and protect the distribution network and the connected loads against short circuits. Typical areas of application are ring main units and transformer stations, wind power and photovoltaic systems, as well as power distributions in industrial plants.

Interview Andreas Matthé

CEO of the Business Unit Low Voltage and Products,
Division Energy Management,
and head of the Siemens booth at Light+Building 2018
Siemens will be appearing at the trade fair under the motto "Digitalize your building". What does this mean exactly?
Digital transformation is fundamentally changing building management. Smart buildings need to be made even more livable and at the same time more efficient to operate. This is where intelligent digitalization solutions, a reliable and efficient power supply, and self-adapting building management systems that are increasingly automated come in. At Light+Building, we will show how digitalization, building management and power distribution systems achieve optimum interaction. This starts with software-based planning and configuration, as well as the digital implementation of system-specific data in BIM (Building Information Modeling), and includes the demand-oriented protection of power distribution systems, for example, as well as the systematic recording of energy and system data during operation of the building. The data integrated in our cloud-based IoT operating system, MindSphere, is available for additional building management tasks. It also enables data-based services, such as performance analyses or power benchmarking.

What opportunities do digital buildings offer?
Digital buildings are energy consumers – and at the same time generate and store energy. They minimize the energy they require and communicate with the entire power grid. This makes them "prosumers", producing and consuming energy at the same time. Prosumers play a key role in the field of transformational energy systems. Integrated building management systems make energy consumption in a building transparent. The detailed data of a building provides the basis of sustainable cost and emissions reduction.
In digital buildings, for example, plants and systems can be predictively maintained, thus preventing downtimes and damage in advance. Digitalized buildings also offer advantages for building users as well: productivity, comfort and safety can be significantly boosted by means of intelligent building management systems. New solutions such as indoor navigation, for example, help users quickly find conference rooms or equipment or show each employee the best route in case of evacuation. Digital buildings are communicating buildings, continuously generating data. We convert this data into knowledge. Knowledge that equips our customers for the future and increases their competitive edge.

What role do power distribution and consumption play in Smart Buildings?
With digitalization, the number of electric loads is also increasing. Firstly, it has to do with power distribution: Modern electrical devices, a growing number of communication and multimedia devices, as well as the use of renewable energies, charging solutions for electric vehicles and increasing automation require new concepts in power distribution and electrical installation. All plants and systems must be coordinated with one another and must be networked. There are ever more stringent requirements in terms of safety. Through innovative solutions, we assist our customers in implementing safe, standard-compliant and communication-capable power distribution. Moreover, we offer innovative and efficient solutions and services to optimize energy consumption and thus increase the long-term efficiency of buildings. In this, our systems also ensure that the optimization of heating, ventilation and lighting goes hand in hand with a perfect room climate.
