ABB Residual Current Device DDA200 Series 25A 2-Pole 30mA Type A 1kA Breaking Capacity 400V AC DDA200

ABB DDA200 Residual Current Device (RCD) with model code DDA200 and MPN 2CSB202401R1250 is a 25A, 2-Pole RCD designed for earth leakage detection and protection. It operates at a rated AC voltage of 400V with a trip sensitivity of 30mA and Type A tripping characteristics ensuring detection of AC and pulsating DC residual currents.

Engineered for both industrial and residential environments, this device is suitable for assembly with S200 series MCBs, allowing modular system integration on DIN rails. The compact design with dimensions 85mm height, 69mm width, and 93mm depth supports versatile installations in control panels and distribution boards.

The device features an instantaneous break time electromagnetic tripping mechanism and a toggle switch actuator for manual reset after trip events. The breaking capacity is rated at 1kA, enabling it to safely interrupt fault currents without damage.

Conforming to IEC/EN 61008 and RoHS standards, the ABB DDA200 ensures compliance with international safety and environmental regulations. Screw terminals provide secure electrical connections for reliable operation over time.

Applications range from residential and commercial buildings to industrial electrical installations where person and equipment protection from earth faults is critical. The RCD offers protection against sinusoidal alternating earth fault currents, indirect contact, and additional direct contact protection at 30mA sensitivity.

Rated current: 25A with 2 poles for moderate load circuits. Earth leakage sensitivity: 30mA Type A for AC and pulsating DC protection. Breaking capacity of 1kA for high fault current interruption capability. Compact DIN rail mountable design to integrate seamlessly into panels.

Instantaneous electromagnetic trip for immediate disconnect upon fault detection. Manufactured in Italy reflecting premium build quality. Meets IEC/EN 61008 electrical safety standards and RoHS environmental compliance.

This ABB RCD DDA200 Series product is a vital component for enhancing electrical safety by timely disconnecting fault currents, reducing shock hazards, and preventing electrical fires. It is a trusted solution in electrical distribution systems supporting safe operation and regulatory compliance.
