2CSR256040R1254 ABB - DS203NC C25 AC30

The ABB DS203NC C25 AC30 is a compact, three-pole plus neutral (3P+N) magneto-thermal differential circuit breaker from the DS203NC series. This device provides comprehensive protection against short circuits, overloads, and earth fault currents. It has a breaking capacity of 6kA, ensuring reliable performance in residential, commercial, and industrial applications. The 'C' curve tripping characteristic makes it suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. It is rated for a current of 25A and trips at a residual current of 30mA, offering enhanced safety against electrical hazards. The AC type designation indicates its suitability for alternating current systems. This MCB combines the functionalities of a miniature circuit breaker (MCB) and a residual current device (RCD) in a single compact unit. This combination saves space in electrical panels and simplifies installation. The DS203NC series is designed for easy installation and reliable operation, contributing to the safety and efficiency of electrical installations.
