RCD-blocks
DDA 200 series B y type

DDA 200 type B for continuous type fault currents
RCD-blocks type B are also sensitive to continuous or mainly continuous (continuous with
weak ondulation) current pulsating earth fault currents. They are also sensitive to alternate
sinusoidal and direct pulsating earth fault currents as with type A circuit breakers.
They satisfy the requirements of type A devices and thus the requirements for type AC
devices which can be considered an extension. For this reason the differential blocks
DDA 202
type B are sometimes referred as “universal type”, as sensitive to “all” kind of residual
current shape.
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
Surge current resistance (8/20 wave): 3000 A
