2CSB203101R1630 ABB - DDA203 A-63/0.03

The 2CSB203101R1630 ABB - DDA203 A-63/0.03 is a residual current device (RCD) designed to protect against electrical shocks and fire hazards. It is a two-pole device, meaning it interrupts both the live and neutral conductors in the event of a fault. The 'A' type RCD is sensitive to alternating current (AC) residual currents. It has a rated current of 63A, indicating the maximum current it can handle under normal operating conditions. The tripping sensitivity is 0.03A (30mA), which is a common sensitivity for personal protection. This sensitivity ensures rapid disconnection of the power supply when a leakage current exceeds this threshold, minimizing the risk of electric shock. The DDA203 series is known for its reliable performance and compact design, making it suitable for various residential and commercial applications. It is typically installed in distribution boards to provide supplementary protection to circuits and equipment. ABB is a reputable manufacturer of electrical equipment, ensuring the quality and safety of this RCD. This device contributes significantly to electrical safety by quickly detecting and interrupting fault currents.
