2CSR273001R1135 ABB - DS203 M AC-B13/0.03

The DS203 M AC-B13/0.03 is a three-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO), meticulously engineered by ABB to ensure comprehensive electrical safety. This device expertly combines the functionalities of a residual current device (RCD) and a miniature circuit breaker (MCB), providing protection against both overcurrents (overload and short circuit) and earth leakage currents. Designed for AC systems, it promptly interrupts the circuit upon detecting a fault current of 0.03A (30mA), mitigating the risk of electric shock. The B-characteristic tripping curve ensures reliable protection for residential and light commercial applications with moderate inrush currents. With a rated current of 13A, this RCBO is suitable for protecting circuits powering lighting, appliances, and general-purpose outlets. The DS203 series is known for its compact design, facilitating easy installation in distribution boards and consumer units. ABB's commitment to quality ensures that this RCBO meets stringent international standards, guaranteeing reliable performance and long-term durability. This device enhances safety in electrical installations, preventing electrical hazards and ensuring the continuity of service. It is an ideal choice for modern electrical systems prioritizing safety and efficiency.
