The variety of residual current devices has continuously increased in last decades
following the technology evolution and the massive introduction of electronics in
all fields of applications.
According to the capability to detect different waveforms of residual current and
the relative sophisticated type testing, today the spectrum of RCDs types covers
from pure AC loads up to high frequency and DC related applications with an
increasing level of protection passing from AC types up to F and B types.
