  • Description

The ABB 2CSB203001R3630 is a DDA203 AC-63/0.3 residual current device block rated 3P, 63 A, 300 mA, Type AC, with instantaneous tripping. It clips onto a System pro M compact S200 or S300P miniature circuit breaker to add earth-fault protection without a separate RCCB, occupying 7 DIN-rail module positions and sharing the host breaker's toggle and trip mechanism.

Selection Notes

The 3-pole configuration suits three-phase circuits with no neutral conductor, such as motor or heating-circuit protection downstream of a 3-pole MCB. At 300 mA Type AC sensitivity with instantaneous tripping, the block is intended for standard final-circuit fire and indirect-contact protection rather than for upstream discrimination against a sensitive downstream RCD. Where the protected circuit carries a neutral, the 4-pole DDA204 block is the correct choice instead of this one.
