RCBOs combine residual current and circuit breakers in a single device (RCCB/MCB combination). They protect people from residual currents and installations from short circuits and overloads. The DRCBO 3 series switches operate independently of the mains voltage and are characterized by a high rated switching capacity. Separate indicators provide a quick overview of the current operating status. DRCBO 3 can be easily installed and removed. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches with tripping characteristic B are the standard protection for lighting and socket circuits. Standard switches are designed for circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz. Features: - auxiliary voltage-independent tripping - sensitive to alternating and pulsating direct fault currents (Type A) - compact size for all rated currents - high short-circuit resistance - green-red marking.
