The Doepke DFS4 025-4/0.01-A is a highly advanced residual current circuit breaker designed for use in single-phase and three-phase networks. This four-pole switch provides reliable protection for people, animals, and electrical installations by immediately 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 of up to 125 A. The integrated double-deck terminals allow for the connection of large conductor cross-sections, while the viewing windows for labeling stickers and the multifunctional switch knob with three positions facilitate handling and troubleshooting. The switch is independent of mains voltage and offers high short-circuit resistance, making it a safe choice for various electrical installations.

• Mains and auxiliary voltage-independent tripping for increased safety
• Sensitivity for alternating and pulsating direct fault currents of type A
• High short-circuit resistance for reliable operation
• Easy mounting on DIN rail in any installation position
• Multifunctional switch knob with clear position indicator.
