2CSR273001R1404 ABB - DS203 M AC-C40/0.03

The DS203 M AC-C40/0.03 is a three-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from ABB, designed to provide comprehensive protection against electrical faults. This device combines the functionality of a residual current device (RCD) and a miniature circuit breaker (MCB) in a single unit. It offers protection against overload, short circuit, and earth fault currents. The 'AC' type RCD is suitable for detecting AC residual currents. With a rated current of 40A and a residual current tripping sensitivity of 0.03A (30mA), it ensures rapid disconnection of the circuit in the event of a fault, minimizing the risk of electric shock and fire. The 'M' curve tripping characteristic indicates its suitability for inductive loads and circuits with inrush currents. This RCBO is ideal for use in residential, commercial, and industrial applications to enhance electrical safety and prevent damage to equipment. It complies with relevant IEC standards, ensuring quality and reliability. The DS203 series is known for its compact design and ease of installation, making it a preferred choice for electrical professionals.
