The Doepke DFS4 100-4/0.50-A residual current circuit breaker is a highly advanced safety device designed to protect people, animals, and electrical systems from dangerous fault currents. This four-pole residual current circuit breaker is suitable for both single-phase and three-phase networks and provides reliable disconnection of the power supply in the event of fault currents. With a compact design that occupies only four modular units, the DFS4 is ideal for use in various electrical installations. The devices are capable of monitoring fault currents up to 125 A and are equipped with large double-decker terminals that can accommodate thicker conductor cross-sections. The user-friendly tripping mechanism and the viewing windows for labeling stickers facilitate handling and troubleshooting. The switch is designed for monitoring circuits with a rated voltage of 230 V and 400 V and offers high short-circuit resistance.

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