Dear Evgueny,
Residual current devices - subject of the discussion are classified by
the European Code EN 61008 as follows:
... On the ability of RCDs to function properly in the presence of DC
components in the AC currents...
Class AC - senses alternate current only
Class A - operates if a residual current consists of uni-directional
pulses
Class B - operates o pure DC
For general use class "AC" is used.
A corresponding IEC standard exists as well.
Best regards
Alex
Кстати, интересно, в чем разница маркировки "А" и "АС". :) Не
встречал что-то ни разу кривой отключения АС. Или что это?
