Flexibility with uncopromising Safety
Residual Current Blocks – DDA
The DDA Residual Current Blocks DDA200 and DDA800 facilitates the customers to assemble the product with S200/S800 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. The side plastic clamp permits a quicker assembly of the block on the MCBs, then a button preserves it from possible disconnections.
Main benefits
Apt to be connected with the proper MCB preventing wrong coupling
Fast connection of the incoming terminals of the MCB
The installation is safe as the coupling elements are not losable
Complete range of products, even selective
Remote tripping terminals on 63 A versions
Test pushbutton to check the responsiveness of the device
Main features
Complete protection against all kinds of leakage currents (AC, A, B, A-APR types available)
Rated currents from 25A up to 63 A in DDA200 and up to 100A with DDA800. The 125A are available as factory fitted RCBO s
Sensitivities in 30mA, 100mA, 300mA, 500mA and 1A
Selective devices
