AFD Unit

Siemens’ AFD unit 5SM6 protects human lives and buildings reliably against fires caused by electricity. It’s the first device of its kind that is 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 – one stop safety.
