The DDA Residual Current Blocks DDA200 facilitates the customers to assemble the product with S200 MCBs in order to combine the protection against indirect contacts, offered by a standard RCCBs, with the protection against short circuit and overloads. 

This flexibility is an added advantage for the ones who desire to maintain the stock level at a minimum, providing a solution for wide range of applications with a handful of RCD blocks.

DDA block are mechanically manufactured to prevent an ill coupling between the block and the breaker: in fact, the rating of the block should always be greater or equal than the rating of the MCB.
