Complete Renewal of the Residual Current Operated Circuit Breaker

31.10.2013
Siemens is renewing their entire RCCB series, replacing it with 5SV switches.

The new switches come equipped with additional safety features, are easier to install, and can be retrofitted with additional functions at any time. The first 5SV switch models are available now: A new Type A RCCB for the German market, and a Type AC RCCB for the European market.


A new Type A RCCB of the 5SV series especially for the German market

These switch types have been developed specifically for applications in the residential and office building sector, and help protect against electricity accidents, equipment damage, and fires. The entire 5SV series will be available by the end of 2014.

A standardized busbar system facilitates faster and safer installation than in traditional wiring systems. With the aid of a latching slide, the switches can be conveniently mounted on or removed from a standard mounting rail in a busbar system. The touch protected, integrated contacts protect the installer from electrical shock when connecting the devices.For additional safety, the switching state is indicated with relevant markings on the handle or in a separate display window. For the easy insertion of pin busbars with connection wires up to 35 mm², the RCCBs come equipped with rectangular terminal clamps and funnel-shaped cable entries.

Standardized gaps between terminals in modular widths mean that the devices can optionally be connected via busbars on the top or on the bottom to other protection devices, e.g. line protection or AFDDs. Die basic function of the RCCBs can be easily extended with additional components, like auxiliary switches or fault signal contacts, open-circuit or undervoltage triggers.

Siemens furthermore supplies extensive data on 5SV RCCBs online for electrical layout planners, installers, and switchgear manufacturers to facilitate planning and project creation: You will find CAx data, like dimensional drawings and STEP models, image data, technical product information, and specification texts.

RCCBs are used in power networks up to 240/415 V AC. If a specific residual current is exceeded due to a defective electrical device, RCCBs disconnect the monitored circuit quickly and safely from mains supply, and offer direct and indirect touch protection. RCCBs furthermore help prevent fires caused by ground-fault currents. For many applications, the use of RCCBs has become mandatory in Germany (DIN VDE 0100-410). The new series 5SV residual current operated circuit breaker is certified for use in the European IEC market.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
