Why does Fi Type B offer greater security than Type A?
In addition to the functionality of Type A, Fi Type B also reliably detects smooth DC residual currents and automatically interrupts the current feed-through if necessary. The shutdown function is also ensured if different types of residual current overlap, regardless of:
- Leading edge angle
- occurring suddenly or slowly increasing
Technical mode of operation:
All-current sensitive RCD (residual current device = error protection circuit) with type B sometimes have a second converter core for additional detection of the smooth DC residual currents, which can be equipped with a Hall sensor to directly detect the magnetic field, and / or others Electronics to, for example, better detect (or hide) frequency responses and their current dependencies and thus offer different types for the corresponding application. Type B is also known as AC / DC sensitive.
