DDA 200 series B y type

DDA 200 type B for selective continuous type fault currents
Function: protection against the effects of alternate sinusoidal, direct pulsating, continuous
current and continuous current pulsating earth fault currents with an intentional trip delay
that permits selectivity with instantaneous type devices placed downstream (for further in-
formation on selectivity, see Chapter 3 of Electrical installation solutions for buildings -
technical details).
DDA 203
DDA 200 type B can be coupled with all the S 200 series MCBs.
They are used for protection in installations with electronic equipments according
to EN 50178.

Applications: tertiary and industrial.
Standards: IEC/EN 61009-1 Ann. G; IEC/EN 61009-2-1; IEC 62423 ed.2
