2CSR253001R1634 ABB - DS203 AC-C63/0.03

The DS203 AC-C63/0.03 is a three-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from ABB, designed to provide comprehensive protection against both overload and short-circuit currents, as well as earth fault currents. This device combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit. It has a C-curve tripping characteristic, making it suitable for applications with moderate inrush currents, such as lighting circuits and general-purpose circuits. The rated current is 63A, and the sensitivity to residual current is 0.03A (30mA), offering a high level of protection against electric shock. The DS203 series ensures reliable protection in residential, commercial, and industrial applications. It is designed for DIN rail mounting, facilitating easy installation in standard distribution boards. This RCBO contributes to electrical safety by quickly disconnecting the circuit in the event of a fault, minimizing the risk of damage to equipment and injury to personnel. Furthermore, it helps prevent fire hazards caused by persistent earth leakage currents. ABB's DS203 series is known for its quality, reliability, and compliance with international standards.
