The Doepke RCD is a highly advanced residual current device designed for use in single-phase and three-phase networks. It provides reliable protection for people, animals, and electrical systems by immediately disconnecting the power supply in the event of dangerously high fault currents. The compact design of the device allows for easy installation on a DIN rail and occupies only four modular units. With a high rated current of up to 125 A and a rated residual current of 0.5 A, this switch is versatile in its applications. The all-current sensitivity of type B ensures comprehensive protection against various fault currents, including smooth DC fault currents and mixed frequencies up to 150 kHz. The integrated double-decker terminals are suitable for large conductor cross-sections, making installation easier. Additionally, the free labeling software assists users in labeling, simplifying troubleshooting and maintenance.

• High immunity to operational leakage and fault currents at frequencies from 1 kHz
• All-current sensitive for fault currents with frequencies from 0 Hz to 150 kHz
• Increased surge current and lightning resistance
• Optimized for systems without fire protection requirements
• Suitable for monitoring circuits with 230 V and 400 V.
