Integrated additional device
The integrated additional device, which depends on the auxiliary voltage, detects
smooth DC residual currents. If these currents exceed 6 mA, the additional device

Trips due to leakage currents caused by surge voltage cannot be completely ruled
out. In cases where an interruption of the power supply may lead to potential
dangers for humans and animals or serious damage to property, residual current
protection should be implemented by means of increased surge current strength,
Important information on tripping with pulsating DC residual currents (type A)
Pulsating DC residual currents also contain a constant part (DC) in addition to
tween a pure smooth DC residual current and the constant (DC), spectral part
of a pulsating DC residual current and thus evaluates these in the same way.
If the additional device is active, pulsating DC residual currents will therefore
