Doepke GmbH Residual current circuit breaker all-current sensitive DFS 4 063-4/0.30-B+

The Doepke GmbH all-current sensitive residual current circuit breaker DFS 4 063-4/0.30-B+ is a highly advanced device designed for use in single-phase and three-phase networks. This circuit breaker provides comprehensive protection for people, animals, and electrical systems by immediately interrupting 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 DFS 4 is capable of detecting fault currents of all frequencies up to 20 kHz, thereby offering increased fire protection. The network voltage-independent tripping for type A fault currents and the voltage-dependent detection of smooth DC fault currents and AC fault currents make it a reliable choice for modern electrical installations. The integrated double-decker terminals allow for the connection of large conductor cross-sections, while the tripped position of the multifunction switch lever facilitates troubleshooting. Additionally, a free labeling software supports the marking process.
