Residual Current Device Block DDA202 A-63/0,03 AP-R

The RCD block DDA200 series is suitable for assembly with MCBs S200 series. It assures protection against the effects of sinusoidal alternating and direct pulsating earth fault currents, providing the best compromise between safety and continuity in the service thanks to the resistance to unwanted trippings. Protection against indirect contacts and additional protection against direct (with sensitivity = 30 mA) contacts. Applications: residential, commercial, industrial.
