Residual Current Block DDA203A 63A/300MA (2CSB203701R3630)

ABB 2CSB203701R3630 — The RCD block DDA200 series is suitable for assembly with MCBs S200 series and S300P. It assures protection against the effects of sinusoidal alternating and direct pulsating earth fault currents, protection, against indirect contacts and additional protection against direct (with sensitivity = 30 mA) contacts. It is provided with two additional contacts to be used in emergency circuits for remote opening in positive safety. Applications: commercial, industrial.
