The FI/LS circuit breaker DS201 M C25 APR30 from ABB is a combination of a residual current device (RCD) and a miniature circuit breaker (MCB), providing protection for both people and property. It meets the requirements according to DIN VDE 0100-410 and DIN VDE 0100-530 and protects single-phase circuits against overload and short-circuit currents. The switch is capable of detecting sinusoidal alternating currents as well as pulsating currents with smooth direct fault currents of up to 6 mA, and offers additional protection against indirect contact as well as fire protection with a rated residual current of up to 300 mA. The DS201 M C25 APR30 is designed for use in households, commercial settings, and industry, providing high immunity to disturbances to avoid unwanted tripping. With numerous certifications, this protective switch is suitable for worldwide use and represents an optimal compromise between safety and operational continuity.
