Despite partially lower power consumption, modern electrical devices and an increase in communications and multimedia equipment are giving rise to an increasing power load in electrical installations in buildings, infrastructures, and industrial plants. Aging and insufficient protection devices are frequently unable to meet these requirements. In addition to the threat of electric shock, function failure, or the destruction of electrical systems, deficiencies and excessive power loads primarily lead to a risk of electrical fires. Rely on an intelligent electrical installation – and play it safe with protection devices from the SENTRON portfolio.
According to the international standard IEC 60364-4-42, AFDDs are strongly recommended all over Europe as the recognized state-of-the-art technology in specific application fields. With the publishing of the standard DIN VDE 0100-420, the installation of AFDDs is now mandatory for many locations in Germany. The 5SM6 AFD units from Siemens are the first arc fault detection device brought to the IEC market that have been providing safe and reliable protection since 2012. The protection devices meet the new standard requirements and form part of Siemens’ comprehensive, end-to-end protection concept. Learn more about these products now!
Expanded fire protection
According to the international standard IEC 60364-4-42, AFDDs (Arc Fault Detection Devices) are strongly recommended all over Europe in specific locations of use.
AFDDs from Siemens can protect functional and public buildings as well as private homes. The 5SM6 AFD unit is the first of its kind that is already established since 2012 and fulfills all relevant rules and standards worldwide, including IEC 60364-4-42. It reliably detects serial arcing faults at an early stage and closes the safety gap to protect human lives and buildings. Moreover, it is part of a complete protection concept by Siemens – that’s one stop safety.
Different types of arcing faults – serial or parallel – can occur. Parallel arcing faults can be caused by such things as aging insulation material or conductive contamination between the phase conductors. Causes of serial arcing faults include damaged cable insulation, crushed cabling, bent connectors, or loose contact points and connections in the electrical installation. The result is intense heating that can lead to a cable fire and even to a fire in the building.
Common protection devices, such as fuse systems, miniature circuit breakers, and residual current circuit breakers are unable to detect serial arcing faults. This problem is remedied by the 5SM6 AFD unit. Using patented SIARC detection methodology, it detects serial arcing faults and closes the previous safety gap.
According to the international standard IEC 60364-4-42, AFD units are strongly recommended for example in woodworking industries!
The 5SM6 AFD unit from Siemens can be used anywhere that requires extra safety – from chemistry labs to daycare centers.
