The Doepke DFS4 080-4/0.03-A residual current circuit breaker is a highly advanced safety device designed for use in single-phase and three-phase networks. This four-pole residual current circuit breaker 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 ideal for applications where space is limited. The devices are available in various versions and support rated currents up to 125 A. The integrated double-decker terminals allow for the connection of large conductor cross-sections, while the switching position indicator and the viewing window for labeling stickers facilitate handling and troubleshooting. The switch is designed for a rated voltage of 230 V and 400 V and offers high short-circuit resistance, making it a reliable choice for various electrical installations.

• Sensitive to alternating and pulsating direct fault currents (Type A)
• Network and auxiliary voltage-independent tripping
• High short-circuit resistance
• Multifunctional switching knob with three positions: on, off, tripped
• Double-decker terminals on both sides for large conductor cross-section.
