  • Description

Rated 4P, 25 A and 300 mA Type AC, the ABB 2CSB204001R3250 DDA204 AC-25/0.3 is a residual current device block with instantaneous tripping. Instead of a standalone RCCB, it clips onto a System pro M compact S200 or S300P four-pole MCB to add earth-fault protection, taking up 6 DIN-rail module positions and sharing the host breaker's toggle.

Selection Notes

Four poles let this block protect a circuit that carries a neutral conductor, which the 3-pole DDA203 cannot do. At 25 A it fits lighter final circuits than the 63 A version in the same DDA204 frame, so the cable cross-section and connecting capacity (0...16 mm² here versus 0...25 mm² on the 63 A block) should be checked against the downstream load before specifying it. Tripping remains instantaneous at 300 mA, giving standard fire and indirect-contact protection rather than delayed selectivity.
