DDA200 range

Safe and flexible installation

The DDA200 RCD blocks, assembled with the S200 series MCBs, provide protection against the effects of sinusoidal alternating earth fault currents, as well as protection against indirect contacts and further protection against direct contacts.

The DDA200 RCD blocks are designed to be installed on the left side of the S200 MCBs, allowing full accessibility of the MCB.
