RCD Add-on Blocks & Earth Leakage Relays

RCD add-on blocks and earth leakage relays from ABB and Schneider Electric add residual current protection to existing MCBs or monitor leakage on a panel. The range includes ABB DDA200 blocks in 2, 3 and 4 poles from 25 A to 63 A, ABB RD2 and RD3 monitoring relays and Schneider Electric Acti9 blocks. Stoklink ships worldwide from Turkey.

What's in this range

• ABB DDA200 RCD blocks that mount on S200 series MCBs, in 2P, 3P and 4P.
• ABB RD2 and RD3 residual current monitoring relays for use with a separate toroid.
• Schneider Electric Acti9 add-on blocks.

How to choose

• Compatibility: the block must match the MCB series, pole count and rated current.
• Function: a block trips the MCB. A relay only signals or trips through a separate device.
• Type: AC or A for the load.

FAQ

Can an RCD block be fitted to any MCB?

No. Use the block specified for the MCB series and pole count. Mixing brands or series is not covered by the manufacturer.

What does a residual current monitoring relay do?

It measures leakage current through a toroid and gives an alarm or trip signal at an adjustable threshold. It does not interrupt the circuit by itself.

Do you ship these to export markets?

Yes. Stoklink ships from Turkey, EXW, and quotes project quantities on request.
