© ABB SACE RCCBs: design F 202 F 362 F 202 New design Differently from the present F3 series, the new F200 series hasn’t any projection on the front side, thus guaranteeing a better homogeneity with MCBs ranges. Moreover the upper and lower shoulders have been eliminated.
© ABB SACE RCCBs: new terminal features Tightening The new terminal has two distinct slots which can be wired. The front slot of the terminal can be wired with cables up to 25 mm 2, while the back one is suitable for wiring with busbars or cables up to 10 mm 2. In the screwing phase, the closing of the two slots is carried out in two opposite directions (bi-directional movement), thus guaranteeing a maximum tightening torque of 2,8 Nm. Closed terminal Open terminal
© ABB SACE RCCBs: new terminal features Wiring The availability of two slots for each terminal offers different wiring solutions thanks to the possibility of deriving independently two cables/each terminal from the same RCCB. The back space, in fact, can be used for another circuit, for an auxiliary circuit or to feed instruments with small section cables without having to connect them in the same space of the power cables.

© ABB SACE RCCBs: new terminal features Safety The structure of the new terminal avoids wrong wiring operations: once the terminal is closed, in fact, the two spaces aren’t accessible anymore.

© ABB SACE RCCBs: new terminal features Plus of wiring with busbars Differently from the past solution, the busbars are fitted in the back terminals slot so that the front side of the terminal is completely visible during the wiring operation. The wiring is now easier for installers and also the accessibility in case of maintenance operations is improved. F 202 F 362
© ABB SACE More Information with PCI RCCBs can support, during their life, high short circuit currents for a short time (until MCBs intervene). Sometimes, owing to repeated short-circuits or in presence of MCBs not opportunely coordinated, the RCCB might be damaged internally and its contacts can result partially welded, and in this case the circuit could be live also in the open position. The presence of the PCI on all products of F200 range guarantees the verification of the RCCB efficiency. RCCBs: positive contact indication (PCI)

© ABB SACE RCD- Blocks: fitting on MCBs In compliance with IEC/EN standard, DDA200 have a new fitting system with clips in order to prevent that RCD-Block could be disassembled once fitted to the MCB.
© ABB SACE RCD-blocks: easier installation assure an easy wiring of MCBs fitted with RCD-blocks with standard busbars allow the possibility to fit MCBs fitted with RCD-blocks on the ways of Type B distribution boarD Housing with holes in the upper side
© ABB SACE RCD-blocks: additional feature add the function of remote tripping to a standard DDA200 block allows space and cost saving for the customer when an auxiliary emergency circuit is needed for an RCBO (MCB+RCD-block) no need for additional shunt trip Additional terminal for remote tripping on 63A size DDA-blocks
