The DRCBO 4 B16/0.03/3N-B from Doepke is a highly advanced combination RCD/MCB that integrates both residual current and overload protection in a compact device. This switch not only protects people from dangerous residual currents but also safeguards electrical installations against short circuits and overloads. With a rated breaking capacity of 6 kA and an all-current sensitive tripping characteristic, the DRCBO 4 is optimized for frequencies ranging from 0 Hz to 150 kHz. This ensures high system availability and minimizes the risk of false tripping. The switch is designed for use in lighting and socket circuits and offers a variety of features, including a switching position indicator and a labeling window that facilitate handling and installation. Its compact design and the option for quick mounting on a DIN rail make it a practical choice for various applications.

• All-current sensitive for residual currents from 0 Hz to 150 kHz
• Low sensitivity to tripping at higher frequencies to avoid false tripping
• Separate indication of the tripping reason for easy fault diagnosis
• Terminal blocks with a wide clamping cross-section range for flexible connection options
• Optimized for systems without fire protection requirements.
