The DS800 range (DS800S, DS800N) consists of factory assembled DDA 800 blocks with S800 MCBs and is available as 2P, 3P and 4P devices. Suitable for industrial applications, this solution is sensitive to earth fault currents and provides protection against overload and short circuit currents.
Specifically, the DS800 series offers several types of protection: type A (pulse current sensitive residual current device), type AS (pulse current sensitive residual current device - selective) and type A-AP-R (pulse current sensitive residual current device - short time delayed).
