ABB DDA803 RCD Block — 3-Pole, Type A, 63 A, 300 mA, Selective, for S800 MCB

The ABB 2CSB803201R3630 is a DDA803 residual current device (RCD) block from the DDA800 range. It assembles on site onto an ABB S800 series miniature circuit breaker and adds residual-current protection to that breaker's overcurrent protection. Building a board this way means the earth-fault function can be added only to the ways that need it, instead of holding a separate RCBO in every rating. It is 3-pole, rated 63 A, with a rated residual current of 300 mA. Type A means it responds to sinusoidal AC residual currents and to pulsating DC residual currents, which is what circuits feeding electronic loads require. At 300 mA it is intended for protection against earth-fault fire and for equipment protection, not for protection against direct contact — that requires a 30 mA device. This is the selective (S-type) version. It trips with a deliberate time delay so that an instantaneous RCD downstream clears the fault first and only the affected circuit is lost — the reason a selective device belongs at the head of a board rather than on a final circuit. Rated voltage 400 V AC; 415 V AC; 690 V AC. It fits S800P, S800S, S800N, S800C and S800B miniature circuit breakers.
