2CSR246040R1164 ABB - DS203NC L C16 AC30

The DS203NC L C16 AC30 is a three-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO) from ABB, designed to provide comprehensive protection against both overcurrents and residual current faults. This device combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single unit, offering space-saving and efficient protection for electrical circuits. It is suitable for residential, commercial, and industrial applications where reliable protection against electrical hazards is essential. The RCBO is designed to trip in the event of an overcurrent, such as a short circuit or overload, as well as when a residual current (earth leakage) is detected, preventing electrical shocks and fire hazards. The 'C16' indicates a 16A current rating, while 'AC30' signifies a 30mA residual current tripping sensitivity. This ensures rapid disconnection of the circuit in case of a fault, minimizing the risk of damage or injury. The 'L' characteristic refers to the tripping curve, providing specific tripping characteristics suitable for various load types.
