Doepke GmbH Residual current circuit breaker all-current sensitive DFS 4 063-4/0.03-B+

The Doepke DFS 4 063-4/0.03-B+ is a highly advanced residual current circuit breaker designed for use in single-phase and three-phase networks. This all-current-sensitive RCD provides comprehensive protection for people, animals, and electrical installations by immediately disconnecting the power supply in the event of dangerously high fault currents. With a compact design that occupies only four modular units, it is ideal for mounting on DIN rails. The switch can detect fault currents of all frequencies up to 20 kHz, making it particularly suitable for applications that require enhanced fire protection. The integrated double-decker terminals allow for the connection of conductors with large cross-sections, while the tripped position of the multifunction switch lever facilitates troubleshooting. Additionally, a free labeling software supports the marking of devices, simplifying installation and maintenance.
