Doepke DFS4 040-4/0.10-F

The Doepke DFS4 040-4/0.10-F is a highly advanced residual current circuit breaker designed for use in single-phase and three-phase networks. This switch provides reliable protection for people, animals, and electrical systems by automatically disconnecting the power supply in the event of dangerously high fault currents. With a compact design that occupies only four modular units, the DFS4 is suitable for both standard applications and more demanding environments. It is capable of detecting various types of fault currents and offers high immunity to surge fault currents. The integrated double-decker terminals allow for the connection of large conductor cross-sections, facilitating installation and maintenance. Additionally, the free labeling software assists users in correctly labeling the switches, enhancing clarity and safety. The switch is rated for a voltage of up to 400 V and offers high short-circuit resistance, making it an ideal choice for various applications.
