2CSR273001R1165 ABB - DS203 M AC-B16/0.03

The DS203 M AC-B16/0.03 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 is specifically engineered to detect both overcurrents (overloads and short circuits) and residual currents (earth faults). The 'B16' designation indicates a 16A current rating with a B-curve tripping characteristic, suitable for residential and light commercial applications. The '0.03' refers to a 30mA residual current tripping sensitivity, offering enhanced protection against electric shock. This RCBO is designed for AC systems and provides reliable protection for people and equipment. It ensures that the circuit is quickly disconnected in the event of a fault, minimizing the risk of electrical hazards. The DS203 series is known for its compact design, ease of installation, and compliance with international standards. It is an ideal solution for modern electrical installations requiring a high level of safety and protection.
