2CSB204001R3400 ABB - DDA204 AC-40/0.3

The ABB DDA204 AC-40/0.3 is a residual current device (RCD) block designed for seamless integration with ABB's S200 series and S300P miniature circuit breakers (MCBs). This combination provides comprehensive protection against electrical hazards in residential, commercial, and industrial settings. Specifically, the DDA204 AC-40/0.3 safeguards against sinusoidal alternating earth fault currents, preventing potential electric shocks and fire hazards. It offers reliable protection against indirect contacts, minimizing the risk of injury from faulty equipment. With a sensitivity of 30mA, it provides additional protection against direct contacts, further enhancing safety for users. This RCD block is particularly effective in detecting and interrupting leakage currents, ensuring a safe electrical environment. Its robust design and compliance with international standards guarantee long-term performance and reliability. The DDA204 AC-40/0.3 is an essential component for modern electrical installations, prioritizing safety and preventing electrical accidents. By quickly disconnecting the circuit upon detecting a fault, it minimizes the potential for damage to equipment and injury to personnel.
