The Doepke DFS4 016-4/0.03-A residual current circuit breaker is a highly advanced safety device designed for use in single-phase and three-phase networks. This four-pole switch provides reliable protection against dangerous fault currents that can endanger people, animals, and electrical installations. With a compact design that occupies only four modular units, the DFS4 is ideal for applications where space is limited. It is rated for a voltage of up to 400 V and a frequency of 50 Hz. The network and auxiliary voltage-independent tripping mechanism ensures additional safety, while the large double-decker terminals allow for easy installation and connection of large conductor cross-sections. The multifunctional switch knob with three positions facilitates operation and troubleshooting, while the viewing window for labeling stickers enables clear identification.
