2CSB203201R2630 ABB - DDA203 A S-63/0.1

The ABB DDA203 A S-63/0.1 is a residual current device (RCD) block designed for seamless integration with the S200 series of miniature circuit breakers (MCBs). This combination provides comprehensive protection against electrical hazards, specifically sinusoidal alternating and direct pulsating earth fault currents. The DDA203 A S-63/0.1 ensures rapid disconnection of the circuit in the event of a fault, minimizing the risk of electric shock and fire. It features a selective tripping delay, allowing for coordination with other protective devices in the electrical system. This selectivity prevents nuisance tripping and ensures that only the faulty circuit is isolated. The RCD block is rated for a maximum current of 63A and has a sensitivity of 0.1A (100mA), providing a high level of protection against earth leakage currents. Its robust design and reliable performance make it suitable for a wide range of applications in residential, commercial, and industrial settings. The DDA203 A S-63/0.1 enhances the safety and reliability of electrical installations by providing effective earth fault protection. It is an essential component for ensuring compliance with electrical safety standards.
